Because of the GIL, thread pools are not as useful in Python as you
might expect -- they execute one at a time and do not take advantage of
hyper-threading or multiple processors. If that kind of efficiency is
what you are after, then take a look at PyLinda which can coordinate
communication between multiple instances of Python running in separate
threads:

FWIW, I wrote a small enchancement to the Queue module that makes it a
little bit easier to use a pool of worker threads and then be able to
tell when they are all done with processing:
