Vinod Kumar Vavilapalli resolved YARN-2055.
    Resolution: Not A Problem

Between YARN-2074, MAPREDUCE-5956 and YARN-2022, this is not much of an issue 

For the remaining toggle of AM containers between nearly full-queues, not much 
can really be done.

I am closing this as not-a-problem anymore, please reopen as necessary.

> If Queue A does not have enough capacity to run AM, then AM will borrow
