ae58649721 Issue #22043: time.monotonic() is now always available 
threading.Lock.acquire(), threading.RLock.acquire() and socket operations now
use a monotonic clock, instead of the system clock, when a timeout is used.

7be74cffbe Remove the obsolete MAXFD constant and Popen._close_fds() method. 
They should have been removed years ago when removing the old pure
Python implementation from the file.

b218863012 subprocess's Popen.wait() is now thread safe so that multiple threads 
may be calling wait() or poll() on a Popen instance at the same time
without losing the Popen.returncode value.  Fixes issue #21291.

016b9e38f7 Use a larger amount of data for tests such as the interrupted_write 
tests that depend on filling up an OS pipe so that they work properly
on systems configured with large pipe buffers.

Also a subprocess docstring update that i forgot was in my client when
i did the original 3.3 commit... easier to just leave that in here
with this one than go back and undo/redo.
