Threads - where to start?

[firephreek]

A while back I posted asking about a problem I was having with some threads.
Somebody responded back with a link to a slide show, but with the little bit
of background I have in this subject, I wasn't able to come away with a
whole lot, much less a solution to my problem.  Where can I go if I want to
get a good understanding of threads and how to implement them?  I'm not sure
what exactly is meant by blocking or locking, or when they should be
implemented. Most of the examples I've read through seem to use the
'threading.py' module as a base for their own class of threads.  Is this the
purpose of threading.py?  Or can it be used standalone?  What about
communicating across threads?  Do they have their own namespace?  Can they
refer to globals in the main program?  Why won't some of them just die?  

I have a lot of questions, but I just don't know where to go!  Help!
