This of course is subject to a race -- the chaff may not execute before the gcc has spun off a child or two.

I like this one *much* better, it is functionally equivalant to cpuselect, if one puts parens around the whole thing to keep chaff from infecting with a bias subsequent commands.
It ideal solution might be to add nohup-like capability to the existing chaff command:
./chaff 0x6 $$ 1234 43213 ... lots of other pids ... (note my proposed reversal of pid & bias) ./chaff 0x6 -c gcc -c module.c
