Nevermind... pid provider... get to have pid hardcoded, or at least as a macro variable. Dropped a brain cell, I guess.
What about taking some cues from Brendan's scripts and imbed the D script in a shell script. But the problem of course is getting the D script started in time. Could you introduce a shell script, with the same name as the program that is being called, that in turn calls the real program using DTrace?
