Just to be clear, my variant of the netbsd-1-6 branch, which I'm using
in production on all those machines, includes some/most/all of Michael's
pmap.c patches.

The occasional crashes I see may be bugs in other parts of the kernel,
probably MI, and they may or may not already be fixed in -current.  Time
will tell.

Hopefully I'll find time to get the whole netbsd-4 into shape with my
private patches I have for my own production use and soon move to using
it.  My need to use netbsd-1-6 for production really has nothing to do
with anything other than that it's where I've spent the most effort to
date at applying local changes which facilitate my own production needs.
