Gabriel Genellina <gagsl-py2 at yahoo.com.ar> added the comment:
At interpreter shutdown, the module's global variables are set to None
before the module itself is released. __del__ methods may be called in
those precaries circumstances, and should not rely on any global state.
A temporary fix would be to make Popen._internal_poll and
Popen._handle_exitstatus keep a reference to the os module (just add a
default argument os=os, like sys=sys in __del__). But this is just a
hack; the real fix would be to avoid defining __del__ at all.
A patch for subprocess.py is attached.
