I wonder if many other people experience the same troubles I do with
   nfe(4).  The attached patch makes it stable for me.  Well, stable to
   the amount of my testing:  previously, cvs up'ing src was enough to
   kill it in a matter of seconds, and now I'm unable to make it trip
   through a cvs up or a rsync of the repository.


excellent work.  this makes nfe(4) stable for me when it previously
would almost always fail when doing disk & network IO.

please commit.
