Doesn't work on Windows (while os.umask() does), as
Windows doesn't have a popen-executable 'umask'.  I
suspect that
    umask=os.umask(0); os.umask(umask)
may be preferable (no portability-loss), although
it does mean there's a timewindow in which the wrong
umask would be used (only relevant on multithreaded
Python programms, I think).
