> TestFastFailWithoutTestUtil has a unit test that does testInterceptorIntercept50Times
Usually it passes but on occasion, the latching between thread 1 and thread 2 goes awry and
the test hangs and the test hangs out. Depends on the hardware but it seems to happen about
one in four runs here on an internal rig.
> HBASE-14421 changed the wait-on-latch to timeout and do a thread dump and just let the
test keep going.
> This issue is about digging in on figuring why the hang up on latches and then fixing
it so the test doesn't have to have the latch timeout. Hopefully the threaddump helps.
> This one could be hard to fix since it not easy to reproduce. Marking it beginner anyways.
