I'm also not sure it's really "newer NetBSD".  I've been seeing
occasional spurious userland coredumps on SS1, SS1+, at least one of
{SLC,ELC}, since pre-1.4.  They weren't frequent; a "make build" (which
in those days took about a day on such a machine) would usually die,
but only once (restarting would finish the run).  When I was using such
a machine as my screen-&-keyboard at work, my X server would die from
it intermittently, probably about once a week average over the long
term.  I also once had a picture-display program that did dithering
corrupt a small section of a picture - it appeared that about 8 bytes
had been replaced with random junk.

The most reliable way to reproduce it I found was found serendipitously
when I tried to host a mud on such a machine.  I never got it to last
long enough to start accepting connections; it always died during
startup.

I basically just stopped using "older" machines, machines that suffered
from it, so I stopped noticing it.  But it isn't new, unless I've
misunderstood the problem.
