-----------------------------------------------------------------
I did a quick profiling session of b885130 (with rows 50 to save some time)
versus the commit immediately prior and they both look very similar. See
attached 'at-HBASE-11331.html' versus 'pre-HBASE-11331.html'. Are you able to
blame HBASE-11331 repeatably [~devaraj]? What differences are you seeing
between it and prior?
