We have a utility called KILL.EXE which simply calls DosKillProcess.  It
has never failed for me.

I have never heard of one, and I think it would be extremely difficult to
write one due to the fact that there can be multiple data segments.  I'm
not typically a Unix programmer, but if I recall properly (correct me if I'm
wrong) fork()'s children inherit everything from the parent including their
very own copy of the data block (and if you order now, we'll throw in a
free disk pack... ;) .

I don't know the reason why os/2 doesn't have fork() but it ISN'T because
there are multiple data segments.  Although they are now obsolete, there
used to be UNIX systems which ran on 80286 systems.  These systems allocated
a new segment each time you called sbrk().  They had no problems with fork().
