[issue20057] wrong behavior with fork and mmap

[STINNER Victor]

STINNER Victor added the comment:

This issue is not specific to mmap. Many other functions and libraries may
use private inheritable file descriptors. Python 3.4 does not fix the issue
for third party libraries.

os.system() must be avoided, use subprocess.call() instead. It avoids an
useless shell process and closes all fds by default.

Is it a documentation issue?
