I don't see this as a bug.  The behavior is the same as the behavior that would 
result if those purgeable tombstones had in fact been purged.  So the request 
here is saying, "give me extra protection if compaction hasn't done its job and 
cleaned these up yet, even though it could have".

This is another (or the same) example of why it's important to do repairs in 
less than gc_grace_seconds.

Is it confirmed whether CASSANDRA-9261 fixed this?  Should this be closed?
