------------------------------------------------------------------

Right on the OOM.  Modified to use a counter instead.

Maybe the WrappedRunnable should be replaced with a Runnable and the decrement should happen in a finally.  But if there is an IOException during the Table.apply(), we probably have far worse problems than non-recovery.

> "drain" will flush and not accept more writes, leaving the commitlog empty on restart.
