* zlib uses an UINT32_MAX sliding window for the output buffer
These funtions have an initial output buffer size parameter:
- zlib.decompress(data, /, wbits=MAX_WBITS, bufsize=DEF_BUF_SIZE)
- zlib.Decompress.flush([length])
If the initial size > UINT32_MAX, use an UINT32_MAX sliding window, instead of clamping to UINT32_MAX.
Speed up when (the initial size == the actual size).
This fixes a memory consumption and copying performance regression in earlier 3.10 beta releases if someone used an output buffer larger than 4GiB with zlib.decompress.

The `try` statement was missing a colon and therefore was not exemplifying the correct `SyntaxError`.

I tried to be relatively thorough and give lots of links.
One reason is that this wasn't deprecated very long; also it seems people running into this tend to not be familiar with similar APIs.

Py_RunMain() now resets PyImport_Inittab to its initial value at
exit. It must be possible to call PyImport_AppendInittab() or
PyImport_ExtendInittab() at each Python initialization.

No longer use len() to get the length of the input data. For some buffer protocol objects,
the length obtained by using len() is wrong.

Fix asyncio test_popen() of test_windows_utils by using a longer
timeout. Use military grade battle-tested test.support.SHORT_TIMEOUT
timeout rather than a hardcoded timeout of 10 seconds: it's 30
seconds by default, but it is made longer on slow buildbots.
WaitForMultipleObjects() timeout argument is in milliseconds.
