The perl code below will generate a ~96MB message and send it to
RabbitMQ via STOMP.  The exchange and destination need not even exist
on the server -- just as long as there's a valid vhost.  Once the
message is sent, RabbitMQ v1.6.0 will crash before the STOMP client
has a chance to even disconnect.

Please let me know if you're able to replicate the problem.  Once you
or Tony has an initial patch, I would recommend testing this code
against the following scenarios:

1) Sent to a non existent exchange
2) Sent to an existing exchange but with a non-existent destination (queue)
3) Sent to an existing exchange and existing non-durable queue
4) Sent to an existing exchange and existing durable queue

Repeat 1-4 with both persistent and non-persistent messages.
