@keith-turner - I don't think this is working as some of the ITs are
failing. It looks like the ITs that are failing are timing out trying to delete
the table at the end of the test method. `ShellServerIT.listCompactions` is one
of the tests that is failing. I was able to grab a stack trace of the
TabletServer right before the test method timed out and it looks like the minor
compaction thread can't complete because it's trying to acquire the lock, which
has been acquired by the thread trying to unload the tablet.
