Donald Smith commented on CASSANDRA-6666:
-----------------------------------------

I know this is moot because of the redesign of hints, but I want to understand 
this. OK, if a hint was successfully delivered, then I can see how a tombstone 
would be useful for causing deletion of *older* instances in other sstables.  
But if a hint timed-out (tombstone), then any older instance will also have 
timed out (presumably). So, could tombstones be deleted in that case (timeout)? 
 Perhaps a timed out cell IS a tombstone, but my point is: I don't see why they 
need to take up space.

> Avoid accumulating tombstones after partial hint replay
