Hmm that's strange.  I don't really see why this would
deadlock.  Could you supply a little more information
about your setup?  Are you using the
SocketInitiator/Acceptor or the Threaded versions. 
Which application callback are you responding to?  Are
you just listening for messages on fromApp, cracking
them and responding?

Concerning DOs and DONTs, I'd actually like to set up
a Wiki at some point.  I think this would be a good
way for users to share their experiences and usage
patterns.
