If I don't do all your work for you to improve your OS, it isn't
my fault. You should take it as a challenge to improve the results
of your project, just as I do mine.

What VM fix are you talking about????  If you are talking about the
FreeBSD code, there is really no fix, but a rework.  If you are talking
about that silly 1second bug in the NetBSD VM code eons ago that
I helped you guys with, that wasn't even a fix.  The VM code at that
time was so far gone as to be not worth fixing, and you guys are
moving to follow that route that I knew long ago was the only real
solution.

I chose to fix the VM code, by making it work as advertised, and
you guys ended up rewriting alot of it from scratch.  So what?

Lesson:  VM code doesn't just page to/from backing store, and excessive
paging is indeed an edge condition that happens often enough to warrant
handling correctly as opposed to punting.
