   I added code in #5395 to interrupt compactions threads and updated the new 
IT there to test this case.
   
   If we wanted to get aggressive w/ troublesome compaction threads we could 
introduce the concept of zombie compaction threads where close will eventually 
abandon a compaction thread.  However it will only do so if it can atomically 
confirm the thread is not making a metadata update and ensure the thread can 
never make a metadata update.  Could probably make all of these changes in 
CompactableImpl.  In general would probably want metrics for zombie compaction 
threads like the zombie scan threads metrics, so those changes would end up 
being outside of CompactableImpl.
