Jonathan Ellis commented on CASSANDRA-5658:
-------------------------------------------

I thought we had a warning for when we have to drop a mutation on the floor b/c 
the table doesn't exist yet.  If you don't see anything like that in the log we 
should probably add it back.  (And if it is in the log, we should add a Tracing 
entry as well.)
