Yes.

I have about a mid-sized heatsink/fan.  It does get much warmer than the p5
ever did, this very probably could be heat related (I hope so... at least that
is easily fixable...  I got an increase in speed almost exactly proportional
to the processor speed difference, with only changing the CPU and not getting
other faster components as well).

I saw a cyrix cooler for 200 MHz cyrix processors.  I will go grab that and
see if that helps at all.

Thanks for the help, I was (am still) really hoping it would be an easily
fixed problem.  BTW, the results of the multiple make world tests with March
27 kernel:
1st -> ok (2.25 hrs) [ this one was a test to see if it would lock up]
2st -> ok (2.25 hrs) [ these were automated ]
3nd -> ok (2.25 hrs)
4th -> lockup about 1.25 hours into it.

tested like:

for a in 1 2 3
{
  # faster to clean most of the cruft out first.
  rm -rf /usr/obj/*
  chflags -R /usr/obj/*
  rm -rf /usr/obj/*
  make world
}

Real Programs don't use shared text.  Otherwise, how can they use
functions for scratch space after they are finished calling them?
