I get strange behavior. Not an error/exception, but basically hung 
process. I tried modifying different things, and passing other types of 
messages. Seems almost like the call to send is ignored for sending the 
s message.

Tried various things, but receiveOnly appears broken for me. I've sent 
messages that should cause an exception and it just hangs.
