Do not log some python smtpd channel messages when debug level 9 is enabled
Multiprocessing debug logging support, new wallace cmd parameter, more logging
Turns out python multiprocessing module can end up in a deadlock situation and wallace accepts messages, but does not start processing them. The real reason of deadlock is not yet known, but the solution is to have more processes started and allow each process to do more job (process more messages) before it is closed and new process added to the pool. That way there is a less chance of deadlock to happen. That is way new cmd parameter --threads is introduced.
