I was running along, minding my own business one day when I got
this message on the console:
Mar  8 15:30:35 tome /netbsd: DANGER WILL ROBINSON: FEN SET IN cpu_fork!
Mar  8 15:30:37 tome /netbsd: DANGER WILL ROBINSON: FEN SET IN cpu_fork!

Jason said I should send-pr it so it wouldn't be forgotten. Sorry, but
I just remembered this, so I'm filing the pr now. The machine was running
1.4.1 at the time, I can send the kernel config file if needed.

   Boot my Alpha running 1.4.1. Wait, but do not hold your breath (it only
   happened once).
   You got me.
