The behaviour of treating it as nonzero would be expected. What
happens is the opposite of that as I described before: the program
hangs as if it received P_WAIT.


I think that they check explicitly for P_NOWAIT and treat anything
different as zero (P_WAIT). 


The principle of least surprise was violated, IMVHO as a newbie on
that area. :-)
