> Currently the cleaning thread in the compactor does not run on a table or partition while
any locks are held on this partition.  This leaves it open to starvation in the case of a
busy table or partition.  It only needs to wait until all locks on the table/partition at
the time of the compaction have expired.  Any jobs initiated after that (and thus any locks
obtained) will be for the new versions of the files.
