No, in this case, it is not, since you still have to call the kqueue
syscall to poll for the file change.  If you're making a syscall to
poll anyway, why not use do a stat?  Stat would be cheaper for e.g.
NFS, as well (or any other remote file system).

Kqueue isn't the be-all-end-all solution to every problem, Perry.
