The 32-bit (49-day) TickCount relied on in EnterNonRecursiveMutex can overflow
in the gap between the 'target' time and the 'now' time WaitForSingleObjectEx
returns, causing the loop to think it needs to wait another 49 days. This is
most likely to happen when the machine is hibernated during
WaitForSingleObjectEx.
This makes acquiring a lock/event/etc from the _thread or threading module
appear to never timeout.
Replace with GetTickCount64 - this is OK now Python no longer supports XP which
lacks it, and is in use for time.monotonic().

bpo-38662: ensurepip invokes pip via runpy (GH-18901)
The ensurepip module now invokes pip via the runpy module.
Hence it is no longer tightly coupled with the internal API of the bundled
pip version, allowing easier updates to a newer pip version both
internally and for distributors.
This way, any changes to the internal pip API won't mean ensurepip needs to be
changed as well. Also, distributors can update their pip wheels independent on
CPython release schedule.
tracemalloc: 'pretty top' example no longer changes the filename (GH-18903)
I've used this recipe a couple times and the filename editing has always
been less than useful and something I've removed. This is because many
modules end up losing which package they are located in, e.g. `util/date.py`.

[3.7] bpo-39769: Fix compileall ddir for subpkgs. (GH-18676) (GH-18718) (GH-18725)
Fix compileall.compile_dir() ddir= behavior on sub-packages.
Fixes compileall.compile_dir's ddir parameter and compileall command
line flag `-d` to no longer write the wrong pathname to the generated
pyc file for submodules beneath the root of the directory tree being
compiled. This fixes a regression introduced with Python 3.5.
Why was the bug ever introduced? The refactoring to add parallel
execution kept the ddir -> dfile computations but discarded the results
instead of sending them to compile_file(). This fixes that. Lack of tests
meant this went unnoticed..

The change broke the backwards compatibility of parsing behavior in a

patch in 3.7.7.
In https://bugs.python.org/issue27657 it was decided that the previous

bpo-39606: allow closing async generators that are already closed (GH-18475) (GH-18502)
The fix for [bpo-39386](https://bugs.python.org/issue39386) attempted to make it so you couldn't reuse a
agen.aclose() coroutine object. It accidentally also prevented you
from calling aclose() at all on an async generator that was already
closed or exhausted. This commit fixes it so we're only blocking the
actually illegal cases, while allowing the legal cases.
The new tests failed before this patch. Also confirmed that this fixes
the test failures we were seeing in Trio with Python dev builds:

Fedora.
bpo-38374: Remove weakref.ReferenceError from docs (GH-18452)
Reflecting changes to the code, removed weakref.ReferenceError from weakref.rst and exceptions.rst.
Issue submitter provided evidence that the `weakref.ReferenceError` alias for `ReferenceError` was removed from the code in 2007. Working with @gvanrossum at PyCascades CPython sprint we looked at the code and confirmed that `weakref.ReferenceError` was no longer in `weakref.py`.
Based on that analysis I removed references `weakref.ReferenceError` from the two documents where it was still being referenced: `weakref.rst` and `exceptions.rst`.
