XMLRPC calls don't work in threads, or rather, they don't play well with others ! (help)

This is unlikely. xmlrpclib does not use threads. I don't know what
xmlrpclib_auth is, so all bets are off.

If it doesn't use any threading facilities, either, blocking calls
will occur eventually only in the socket read/write calls, which do
allow other threads to run, and do release the interpreter lock
properly.

I'd add print statements at all levels of the code, to see where
exactly it is blocking.
