It should only affect windows emulated tasks, nothing else. If you want
to do locking friendly behaviour you could also take lockf locks so that
Linux domain code that *wishes* to be nice in this area behaves the way
you want.

Without that you break so much stuff its a horrible idea (eg backups,
ubuntu one sync etc).
