> Per [~devaraj]'s idea on parent issue, let's see if we can reduce the scope
> of critical section under which compactions hold the region read lock.
> Here is summary from parent issue:
> Another idea is we can reduce the scope of when the read lock is held during
> compaction. In theory the compactor only needs a region read lock while
> deciding what files to compact and at the time of committing the compaction.
> We're protected from the case of region close events because compactions are
> checking (every 10k bytes written) if the store has been closed in order to
> abort in such a case.
