Stu Hood commented on CASSANDRA-685:
------------------------------------
> Would this back-pressure apply to commit log replay?
It seems that one of the reasons why commit logs get large in the first place
is because we don't have backpressure, so I think this should fix the problem
indirectly by preventing huge commit logs.
> add backpressure to StorageProxy
