Interesting. That implies you don't actually want some fixed thresholds 
per queue but a means for rabbit to automatically evict some messages 
when disk space becomes tight. Though some per-queue controls are 
perhaps desirable for this as well, so that rabbit can be guided as to 
*which* messages to evict.

Say you have a whole bunch of queues with varying amounts of data, 
message ages, and throughput. And now rabbit notices that it is about to 
run out of disk space. How should rabbit go about deciding which 
messages to evict?

Your thoughts on this are much appreciated.

Regard,

Matthias.
