I like the approach that Sturla mentioned: using closures to implement
worker threads. I think that's very pythonic. You could do something like
this, for example:
for item in queue:
Note that the queue is only needed to tell the thread what to work on. A
lot of things can be shared over the closure. So the queue may not even be
required in many cases.
