We have a winner.

So is it then true in general (I am almost 100% sure that it is) that in
between the commitinfo/verifymsg scripts getting executed and the
loginfo script getting executed some other program in the system could
come along and grab a PID, thus making the delta between the loginfo
ppid and the commitinfo ppid be greater than 3?

That is, the fact that I'm seeing nothing grabbing a pid inbetween the
fork and exec calls doesn't mean that something COULDN'T grab a PID at
that point.  SO I really shouldn't rely on the delta being 3 at all,
should I.
