>
> PendingRepairManager#getScanners has an assertion that confirms an sstable
> is, in fact, marked as pending repair. Since validation compactions don't use
> the same concurrency controls as proper compactions, they can race with
> promotion/demotion compactions and end up getting assertion errors when the
> pending repair id is changed while the scanners are being acquired. Also,
> error handling in PendingRepairManager and CompactionStrategyManager leaks
> refs when this happens.
