Or actually, maybe we should just drop the lstat call altogether?
AFAICS it's 99.99% redundant with the lstat that traverse_datadir
has done nanoseconds before. Yeah, maybe somebody managed to drop
the file in between, but the FILE_ACTION_REMOVE code would have to
deal with such cases anyway in case a drop occurs later.
