when does kill -9 pid not work?

[Marty]

On a sun386 running sunOS4.0, I was playing around with Minix boot disks in
a DOS window.

I had an infinite loop in my boot loader, and I couldn't kill the DOS task
via a
kill -9 pid
which I always though always worked (I tried doing it as rooot after my own
account didn't work).

I did a shutdown (geez, maybe it knows something I don't know) and it said:

"Something is hung--won't die, ps axl advised".

I give up...Was Jason in my machine?
