os.makedirs('foo/x', 0777) does not create the directories
with permissions g+rwx,u+rwx,o+rwx but instead:

>>> import os
>>> os.makedirs('foo/xx', 0777)
>>>

This happens with Python 2.3.4 on Linux

What is the current process umask? The resulting directory
mode will always be (mode &  ~umask  &  0777).
To be sure that os.makedirs() will use the given mode
without modification, you have to execute os.umask(0)
beforehand.

So this bug is probably invalid if you forgot to set your
umask accordingly.

umask(0) does the job. In this case the documentation is
completely misleading. The API reads as the 'mode' parameter
is *the* umask.

Clarified the docs in rev. 41732/41733.
