Increase the timeout: give timeout x 4 instead of timeout x 2 to
threads to wait until the Event is set, but reduce the sleep from 500
ms to 250 ms. So the test should be more reliable and faster!

test_signal.test_socket(): On Windows, sometimes even if the C signal handler
succeed to write the signal number into the write end of the socketpair, the
test fails with a BlockingIOError on the non-blocking read.recv(1) because the
read end of the socketpair didn't receive the byte yet.
Fix the race condition on Windows by setting the read end as blocking.
On Windows, sometimes test_signal.test_warn_on_full_buffer() fails to
fill the socketpair buffer. In that case, the C signal handler
succeed to write into the socket, it doesn't log the expected send
error, and so the test fail.
On Windows, the test now uses a timeout of 50 ms to fill the
socketpair buffer to fix this race condition.
Other changes:
* Begin with large chunk size to fill the buffer to speed up the
test.
* Add error messages to assertion errors to more easily identify
which assertion failed.
* Don't set the read end of the socketpair as non-blocking.
The test failed on AMD64 Debian root 3.x buildbot because the busy
loop of 100 ms only increased time.thread_time() by 19.9 ms which is
smaller than 20 ms. Modify the test to tolerate a delta of at least
15 ms instead of 20 ms.

Change test_logging.SMTPHandlerTest timeout from 8 seconds to 1
minute. The test failed randomly on the slow x86 Gentoo Refleaks 3.7

bpo-34009: Expand on platform support changes (GH-8022)
Many users won't realise the implications the OpenSSL 1.0.2
minimum version requirement has when it comes to Ubuntu
14.04 and Debian 8, so expand on that in the platform support
section.
Also explicitly note the non-ASCII-based locale requirement for
full Unicode text handling support on non-Windows systems.

bpo-28626: rearrange discussion of output formatting to encourage f-strings (GH-6036)
The 'output formatting' section of the tutorial talks a lot about manual formatting with things like .rjust() and .zfill(), with only a passing reference to 3.6's new f-strings.
This doesn't drop all of the old material, but it does rearrange the topics into a more modern order: f-strings first, discussing formatting specifiers a bit; then calling .format(); finally manual formatting with .ljust().

closes bpo-34056: Always return bytes from _HackedGetData.get_data(). (GH-8130)
* Always return bytes from _HackedGetData.get_data().
Ensure the imp.load_source shim always returns bytes by reopening the file in
binary mode if needed. Hash-based pycs have to receive the source code in bytes.
It's tempting to change imp.get_suffixes() to always return 'rb' as a mode, but
that breaks some stdlib tests and likely 3rdparty code, too.

[3.7] bpo-33899: Make tokenize module mirror end-of-file is end-of-line behavior (GH-7891) (GH-8132)
Most of the change involves fixing up the test suite, which previously made
the assumption that there wouldn't be a new line if the input didn't end in
one.
subprocess.Popen now copies the startupinfo argument to leave it
unchanged: it will modify the copy, so that the same STARTUPINFO
object can be used multiple times.
Result of function interpreter_requires_environment() depends on os.environ.
This was not covered by the tests, leading to fail when PYTHONHOME was set.

Fix test_forkserver_sigkill() of test_multiprocessing_forkserver:
give more time to the first child process to complete, double the
sleep in the parent process.
Reduce also the child process sleep from 1000 ms to 500 ms, to not change
the total duration of the test.

bpo-33735: Fix test_multiprocessing random failure (GH-8059)
When hunting memory leaks using -R 3:3, test_imap_unordered() of
test_multiprocessing leaks randomly a few memory blocks. It is a
false alarm: when testing using -R 3:20 for example, no leak is
detected.
Modify test_imap_unordered() to be closer to test_imap():
* Only test 10 numbers instead of 1000: it's a pool of 4 processes, so
10 is enough to test at least one number per process
* Use chunksize=100 instead of chunksize=53 to mimick test_imap()

bpo-32568: make select.epoll() and its docs consistent (GH-7840) (GH-8024)
* `flags` is indeed deprecated, but there is a validation on its value for
backwards compatibility reasons. This adds mention of this in the docs.
* The docs say that `sizehint` is deprecated and ignored, but it is still
used when `epoll_create1()` is unavailable. This adds mention of this in
the docs.
* `sizehint=-1` is acceptable again, and is replaced with `FD_SETSIZE-1`.
This is needed to have a default value available at the Python level,
since `FD_SETSIZE` is not exposed to Python. (see: bpo-31938)
* Reject `sizehint=0` since it is invalid to pass on to `epoll_create()`.
