[issue21618] POpen does not close fds when fds have been inherited from a process with a higher resource limit

[Gregory P. Smith]

Gregory P. Smith added the comment:

Are you aware that the subprocess module does use /proc/self/fd in Python 3.2 and later?  The fd closing is not done from Python code.

See Modules/_posixsubprocess.c - http://hg.python.org/cpython/file/53fa2c9523d4/Modules/_posixsubprocess.c
