[MacPerl] processor hog - nice?

[Pete Prodoehl]

I have a perl script which I've made into a runtime, and it's working great
- except that it's pretty intensive, and tends to lock up the Mac a bit
while it's running... I've added some calls to sleep, but I'm wondering how
I can make it a little more cooperative, sort of like using the nice command
under *nix so it's not a processor hog. 

Is it a perl thing? A Resedit hack? or...?

thanks...

Pete
