No, not a performance issue, but a memory one.  I have a file-based
queue implementation now, and it looks like it's easy enough to drop
into the rabbit_amqqueue_process, with the exception of where it calls
queue:to_list in purge_message_buffer.  I'd like to avoid having to
have the to_list called, and instead just grab a few (thousand)
messages at a time and call extend_transaction on the chunks.
