RabbitMQ starts paging the messages to disc in low memory
situation. Thus, it can handle large amounts of data. The limits are
regulated by the configuration settings `vm_memory_high_watermark',
which determines when the messages will start to be paged to disc; and
`disk_free_limit', which determines the amount of free space below
which RabbitMQ after which the publisher connections will be
blocked.

See http://www.rabbitmq.com/configure.html for docs on the
configuration and http://www.rabbitmq.com/memory.html for docs on flow
control (the system that regulates when the connections are blocked).
