I'm looking at a situation where I have a lot of producers doing work,
but one part of logging the info must be done via a single-threaded
process to avoid deadlocks across the workers.  So basically I'll have
one consumer and a bunch of producers.  The backlog can get large --
I'm not worried about the delay of processing the requests -- but I
need to not lose any requests.

Anyone know if Theo's Net::RabbitMQ perl module honors the
channel.flow?  It appears to be built upon the C client.

What if my producers used the "mandatory" flag to detect if the queue
is full, and then just pause for a while if it is?

If I use a large-RAM box for my queue server, will rabbitmq use more of it?

Thanks.
