Review request for mesos, Benjamin Hindman, Vinod Kone, and Brenden Matthews.


Description
-------

See my comments in the diff.

The benefit of this solution is that the only modification needed is to unsynchronize resourceOffers()
and pull out the needed JobTracker data prior to synchronizing explicitly. Longer term we
will want to consider something more robust against regressions.


This addresses bug MESOS-429.
