Well.. cc said "fatal signal 11"  I just assumed the mmu was saying "nothing
there fred"

Curious, how did you know this?

I'm running the snapshot right now..  I just compiled and booted a new kernel
from current about 4 days ago..  I got this while doing a make build of the
world.  I typed make again, and it happily continued on it's merry way.  I'll
keep building and let you know if I can get it to happen again.  

I used to get fatal signal 11's all the time under i386.. It's incredibly
annoying..  I usually assume it means it hit the ulimit somewhere, and bombed. 
Normally if I just make again, it picks up where it left off and goes on it's
way.
