[bpo-34658](https://www.bugs.python.org/issue34658): Fix a rare interpreter unhandled exception state SystemError only
seen when using subprocess with a preexec_fn while an after_parent handler has
been registered with os.register_at_fork and the fork system call fails.
bpo-34200: Fix non-determinism of test_pkg (GH-9248)
This causes the tearDown code to only unimport the test modules specifically created as part of each test via the self.mkhier method rather than abusing test.support.modules_setup() and the scary test.support.modules_cleanup() code.
closes bpo-34004: Skip lock interruption tests on musl. (GH-9224)
Returning EINTR from pthread semaphore or lock acquisition is an optional POSIX
feature. musl does not provide this feature, so some threadsignal tests fail
when Python is built against it.
There's no good way to test for musl, so we skip if we're on Linux and not using
glibc pthreads.
Also, hedge in the threading documentation about when we can provide interrupts
from lock acquisition.

This also removes the old manual p2cread, c2pwrite, and errwrite closing logic
as inheritable flags and _close_open_fds takes care of that properly today without special treatment.
This code is within child_exec() where it is the only thread so there is no
race condition between the dup and _Py_set_inheritable_async_safe call.

bpo-34588: Fix an off-by-one error in traceback formatting. (GH-9077)
The recursive frame pruning code always undercounted the number of elided frames
by one. That is, in the "[Previous line repeated N more times]" message, N would
always be one too few. Near the recursive pruning cutoff, one frame could be
silently dropped. That situation is demonstrated in the OP of the bug report.

bpo-34246: Use no mutable default args in smtplib (GH-8554)
Some methods of the SMTP class use mutable default arguments. Specially
`send_message` is affected as it mutates one of the args by appending items
to it, which has side effects on further calls.

bpo-34007: Skip traceback tests if the Program Counter is not available. (GH-9018)
Sometimes some versions of the shared libraries that are part of the
traceback are compiled in optimised mode and the Program Counter (PC)
is not present, not allowing gdb to walk the frames back. When this
happens, the Python bindings of gdb raise an exception, making the
test impossible to succeed.

bpo-34454: fix .fromisoformat() methods crashing on inputs with surrogate code points (GH-8862)
The current C implementations **crash** if the input includes a surrogate
Unicode code point, which is not possible to encode in UTF-8.
Important notes:
1. It is possible to pass a non-UTF-8 string as a separator to the
`.isoformat()` methods.
2. The pure-Python `datetime.fromisoformat()` implementation accepts
strings with a surrogate as the separator.
In `datetime.fromisoformat()`, in the special case of non-UTF-8 separators,
this implementation will take a performance hit by making a copy of the
input string and replacing the separator with 'T'.
