I am in a slightly dodgy position here as the 'maintainer' of our NFS
code.  I don't run NFS much here.  I spend most of my time running my
employer's 'operating systems' and even when I do spend a bit of time on
FreeBSD, I only have one machine which can possibly run -current.  I am
perfectly willing to attempt to find and fix problems in the NFS system
but a lot of the time I simply *can't* reproduce the problems that people
are seeing.

It would be extremely helpful if those of you who have NFS problems to
actually get your hands into the code and figure out what is happening in
your environment.  I know this is not always possible but certainly some
of you can.  A good example here is Hidetoshi Shimokawa who had a problem
with write performance, got into the code and found a solution.  This has
two benefits:  better performance for NFS and one more person who
understands (some of) how this monster works.
