Jason Brown commented on CASSANDRA-6503:
----------------------------------------

The followup patch is fine, but I'm not quite sure why it is needed. How does 
being in a different thread affect the sending of the CompleteMessage, which 
doesn't look like it was there before?

> sstables from stalled repair sessions become live after a reboot and can 
> resurrect deleted data

> The sstables streamed in during a repair session don't become active until 
> the session finishes.  If something causes the repair session to hang for 
> some reason, those sstables will hang around until the next reboot, and 
> become active then.  If you don't reboot for 3 months, this can cause data to 
> resurrect, as GC grace has expired, so tombstones for the data in those 
> sstables may have already been collected.
