After re-reading my original post, I explained poorly what was going

To further elucidate:
lines 100-108 of do_command.c in the vixie cron sources say
/* mark ourselves as different to PS command watchers by upshifting
* our program name. This has no effect on some kernels.
*/
/*local*/{
register char *pch;
for (pch = ProgramName; *pch; pch++)
*pch = MkUpper(*pch);
}
This bit happens after the fork as a cron job is about to be executed.
