Unicode version of Windows APIs are used in places, but not for GetVersionEx in Python/sysmodule.c
The wcstok_s is called on Windows in Modules/main.c and PC/launcher.c, but not in Python/pathconfig.c

Make sure that failure paths call CloseHandle outside of the function that failed

https://bugs.python.org/issue32560

LoadLibrary, GetProcAddress, FreeLibrary and GetModuleHandle acquire the system loader lock. Calling these while holding the GIL will cause a deadlock on the rare occasion that another thread is detaching and needs to destroy its thread state at the same time.

Add one char to MsiSummaryInfoGetProperty() output
Based on the patch in bpo-1104 by Anthony Tuininga (atuining) and Mark McMahon (markm).

Use correct interpretation of return value from APIs.

The test fails. Skip the test until a fix can be found.

* Change from OrderedDict to a regular dict

* Add blurb

Close pipes/fds in subprocess by using ExitStack.

"In case of premature failure on X.Close() or os.close(X) the remaining pipes/fds will remain "open". Perhaps it makes sense to use contextlib.ExitStack."

This fixes the ctypes.test.test_structures.StructureTestCase test.

The previous wording could be read as saying that universal
newlines mode itself was deprecated, when it's only the 'U'
character in the mode field that should be avoided.

The update also moves the description of the 'U' mode character
out of the mode table, as the longer explanation was overly
intrusive as a table entry and overshadowed the actually useful
mode characters.
