I considered that but had to stick to ps(1) because pgrep was in
/usr/bin while ps was in /bin.  The use of /usr/bin tools should
be very limited in rc.subr(8).  OTOH, pgrep uses /lib libs only,
which makes it possible to transfer pgrep+pkill to /bin if we can
stand the growth of / by some 50 kbytes.
