kulikjak changed the title ~~gh-113117: Posix spawn close fds support~~ gh-113117: Support posix_spawn in subprocess.Popen with close_fds=True

Dec 14, 2023

Gives a more useful description and mentions that it can be turned off but that we'd like to hear from anyone doing so.

(the joys of using the github web editor)

This describes the module changes in module sections and makes the
Optimizations section brief, referring back up to the subprocess

…ds=True (python#113118)

Add support for `os.POSIX_SPAWN_CLOSEFROM` and
`posix_spawn_file_actions_addclosefrom_np` and have the `subprocess` module use
them when available.  This means `posix_spawn` can now be used in the default
`close_fds=True` situation on many platforms.
