I was thinking about pipelining.  In many cases we do know in advance
a number of files that we'll want to fetch down.  These can be either
pipelined onto a single HTTP connection, or spread across multiple
connections.  

I'm thinking of some kind of producer/consumer or blackboard model
where the main program adds URLs to a queue that it wants, and then
one or more HTTP threads pull them down and eventually mark them as
either complete or failed.

urlgrabber's web page talks about this but it doesn't seem to be
written yet.  Perhaps the easiest thing is to introduce a layer on top
of urlgrabber, since the API for backgrounded/async downloads would be
rather different.

Well done!  I'll merge both these this afternoon.
