So this raises an interesting point...

If the replica N files all have slightly different mtimes (it seems they
usually will because they weren't written at exactly the same time),
then isn't this a point of inconsistency for a script running on a fuse
mount which expects the same mtime on a file?

Shouldn't gluster somehow coordinate to set all the files mtimes to be
consistent to say the last mtime in the replica set?
