> Now we have two chores for mob, one is the cleaner of expired mob files, the other is
for the mob file compactor. They might handle the same file set concurrently, and might impact
each other when doing that. We need to synchronize them, now we have a write lock for the
mob file compaction chore, we need to add a read lock for the chore of expired mob file cleaner.
