I need the FULL change to machdep.c and apparently the chagne to subr_prf.c
is needed too, at least it hasnt broke yet with that in place too, not
that I can see why it matters though.

The new diff to machdep.c that jhb made yesterday also causes trouble.

That is what I've been harping about for months...

What strikes me here as a very serious problem is that the SMPng developers
has told me over and over that it works fine for them on -current, but
when we get to the matter after months of frustration, it suddenly appears
that they are not running the same -current as the rest of us.

Now guys, excuse my language, but that *sucks* bigtime.

However I'm still running tests here, and I'm offering to test every patch
you can come up with to help locate the problem, just as always...
