Fundamentally, you can't have mutable globals in multiprocessing
(though you can have immutables - they'll get copied into each
subprocess). Instead, look into the various data structures like the
queue, which can transfer information from one process to another. The
best option depends a lot on what you're doing - but you can find some
tips and ideas in the multiprocessing module's documentation. (You
HAVE read the docs already, right? :) )
