Seconded. If you know how many threads you're going to have, just open that many connections. If not, there's a connection-pooling feature as part of psycopg2 (if I'm not mistaken). This would be far far easier to work with than a fragile queueing setup. Chrisa -- https://mail.python.org/mailman/listinfo/python-list
