python threads?

[Cole Tuininga]

Unfortunately, you're running into one of the little secrets of
python ... the GIL (Global Interpreter Lock).  While python has support
for "multithreading", it doesn't work the way you would normally think
of threading.  If it still works the way it used to, the python
interpreter basically runs 10 pseudo instructions (barring running into
some kind of blocking call) and then swaps off to another thread.

If you truly want to use multiple processors for a python program,
multi-process with (your choice of) IPC is going to be the way to go.
