Excellent idea. I've begun doing just as you suggested. Currently it
seems to me that this would be an "{$ifdef UNIX}" thing only in
process.pp. The reason I say this is that for the windows and wince
implementations of process.inc I don't see a place this event could be
triggered. The Windows API call CreateProcess is somewhat different
then UNIX's model of fork then exec, in between which I can trigger
the event so it happens in the context of the child process.
