Review Comment:
There is no actual data consumption or modification here at this point so it
should not be sensitive to any concurrent operations for any locking
requirements. We can just check the file existence here without locking and if
it doesn't exist, quickly return with no further operation needed as we already
know without locking that there will be no file to remove.
