Michael Greene commented on CASSANDRA-369:
------------------------------------------

The code looks good after explanation and works when exercised.  I was 
surprised that running stress against against a single node cluster, probing 
that node only ever gives values of 0,1, or 2 for the commitlog--it seems like 
it should have a deeper queue then that.

> Need to expose queue size of CommitLogExecutorService via jmx.  Probably we
