Jonathan Ellis commented on CASSANDRA-894:
------------------------------------------

there's at least one show-stopper bug here; you can't just not do the hinted 
writes in MutateBlocking since remember the hints prefer to go to another 
"natural" replica.  so this patch blows away writes to those natural replicas, 
along w/ the hints.    probably the easiest fix is to leave StorageProxy alone, 
and modify getHintedEndpoints instead.

Making the setting per-CF would be better than global.

Leaving HHOM alone to replay already-existing hints would be better than 
leaving them to rot.
