All current versions of RabbitMQ will page messages out to disk if 
memory starts to become even slightly tight.

The next release (3.2.0 in case someone is reading this on a web archive 
in the future) will make this tunable, so if you really need to ensure 
RabbitMQ never pages messages out you could install a nightly build and 
investigate the vm_memory_high_watermark_paging_ratio configuration item 
documented at http://next.rabbitmq.com/memory.html#memsup-paging - 
setting it to a number greater than 1.0 should disable paging.

Cheers, Simon
