Hey Abe,

hmm, let's see...  I think the easiest way to test for correct threading
is to put in 'time.sleep(n)' statements, so that each connection takes a
long time to be handled.  Then open up multiple connections to the Web
server and make sure that they're handled properly.  The only trick here
is to distinguish between connections that are waiting to be returned
from 'accept' and connections that are in the 'time.sleep' call; you
could put in some print statements to differentiate between the two.

You could also try setting 'listen' to 1 and opening up four or five
connections at once, after you put in a 'time.sleep(5)'.  That will make
sure that the connections are actually being 'accept'ed and not simply
queued up waiting for the 'accept' call to return them.
