I am slowly moving to a model where all process killing is struct pid based
instead of pid_t based.  The sunos compatibility code is one of the last users
of the old pid_t based kill_pg in the kernel.  By being complete I allow for
the future removal of kill_pg from the kernel, which will ensure I don't miss
something.
