there was a change where kthread_create now actually produces new 
THREADS in 8.0
but prior to that it produced new processes..

I THOUGHT that change happenned between 6 and 7 but maybe it was 
between 7 and 8..


do you have a kproc man page?


on 8.0, see:

man kproc
man kthread

on 7.0 I think these will show nothing and you should do:

man kthread_create
