Comment (by anevilyak):
The mtime test fails for a simple reason: BFS intentionally salts the
tv_nsec field in order to generate a more unique distribution for its
last_modified index. Consequently, the nsec field passed in will more or
less never match the one that ultimately winds up being written to disk.
