If RabbitMQ crashes because it's out of memory, I understand that it
should be able to start again without losing any data.  Will the next
message sent to it (before any messages are dequeued) cause the queue
to crash again?  I assume that must be the case, since nothing was
lost when the program crashed.  I don't know what to do about this,
but it may be something to try to plan around.
