Review Comment:
   This is the number of orphan files that were actually deleted no?
   I think -1 as a default is misleading. If orphan files were computed but all 
failed to be deleted, then this is valid to be 0.  If we fail to even compute 
the orphans, we'd just throw an exception and there'd be no result to begin 
with.
