How to know if a module is thread-safe

[Jérémy Wagner]

Hi, I recently tried to use the subprocess module
within a threading.Thread class, but it appears the module
is not thread-safe.

What is the policy of python regarding thread-safety of a module ?

Pretty bad bug, really, since subprocess is supposed to be the
replacement for all the other mechanisms like popen2 and os.popen*

I personally don't know. But any module that's not thread safe would be
a bug in my mind.
