What I did is have the mandatory flag only be set if you give the
ThriftAMQPClient a thriftClientName (which is the convention that
Terry started right)? Again this is all in the thrift stuff.

This is mainly happening while using the thrift portion. It looks
like the thrift portion doesn't use an outgoing queue, correct? It
looks like the result of the thrift flush calls sendMessage which
calls basic_publish (which requires multiple frames, and could get
interleaved and fail). I definitely see the work queue and the
outgoing queue, I am just not sure if I am groking the code correctly.
Thanks again! Hope you are doing great.
