> There is a race condition where SSTables from streaming may race with pending 
> repair cleanup in compaction causing us to cleanup the pending repair state 
> in compaction while the SSTables are being added to it; this leads to IR 
> failing in the future when those files get selected for repair.
> This problem was hard to track down as the in-memory state was wiped, so we 
> don’t have any details.  To better aid these types of investigation we should 
> make sure the repair vtables get updated when IR session failures are 
> submitted
