I haven't seen this, and I do some interesting data reduction
ugliness that eats acres of memory for breakfast, lunch and dinner,
cranking out network statistics.

I haven't seen this either, and I do pretty much the same things
via (NQ)NFS, and some even uglier things to boot.  

Have you done a packet trace to see what's happening during all of this?

I have found a couple bugs with NQNFS, admittedly, and I have just
gotten a new panic lately that I'm scratching my head over.

WRT running NetBSD in a "real environment", there are some deficiencies,
but my opinion is that these seem to be less of a problem than the 
idiosyncracies of the OSes shipped by SUN.  If anyone has NetBSD 
running on SS4s, SS5s and SS10s, I'd really love to know, as some 
colleagues of mine would love to be running NetBSD on their at-work boxes too.

Finally, all the fixes I've seen put together have been pretty solid,
which is a pleasant change compared to what I remember from commercial
vendors...
