> Running an extended serial write test (EvaluationClient), a test that runs long enough
it triggers compactions and splits, hbase falls over.  In the former case, client gets locked
out.  In the latter, the client times out.
> During compactions, hbase should be able to continue to take writes/updates.  During
splits, the client will have to recalibrate so writes go instead into the new splits but again,
other than a pause, writes shouldn't be dropped.
