So here's another idea, applies on top of current -git. Basically it 
makes rbd wait for the oldest event, not just the first one in the array 
of all ios. This is the saner thing to do, as hopefully the oldest event 
will be the one to complete first. At least it has a much higher chance 
of being the right thing to do, than just waiting on a random event.

Completely untested, so you might have to fiddle a bit with it to ensure 
that it actually works...
