Subject: [PATCH] Assume file has vanished if we can't lstat it

A file might be deleted between the time we read the directory and the
time we get around to check it, so if we can't lstat it, assume that is
what has happened. (It might also have been renamed, but that's
equivalent to this file being deleted and another being created, so we
don't have to treat this specially)
