Hi Jonathan,

Thanks very much for all of your work on this release.

I have a concern about cross-queue (inter-queue) preemption in 2.10.

In 2.8, on a 6 node pseudo-cluster, preempting from one queue to meet the needs 
of another queue seems to work as expected. However, 2.10 in the same 
pseudo-cluster (with the same config properties), only one container was 
preempted for the AM and then nothing else.

I don't know how the community feels about holding up the 2.10.0 release for 
this issue, but we need to get to the bottom of this before we can go to 
2.10.x. I am still investigating.

Thanks,
-Eric
