My recommendation is to upgrade rabbitmq-c to v0.4.0. While it is possible
to implement AMQP heartbeats from a client program, it requires in-depth
knowledge of the AMQP protocol, the innards of rabbitmq-c, and likely will
break when you get to the point of upgrading to v0.4.0.

amqp_simple_wait_frame() when the socket is closed. There might be a few
messages in the client-side network buffer that will end up being consumed
by rabbitmq-c before it detects that socket has been closed.
