in reply to Limiting script cpu time

IIRC, you can use the ulimit Unix command to limit cpu time, among other things. Just type man ulimit for more info. Or, for a more perlish solution: 
#!perl
$SIG{ALARM} = sub {die "Time Out!"};
alarm(120); #this script will run for at most 120 seconds

#your script goes here

    i think he/she's after not taking up too much % cpu time; not to kill the script after it's done half the image. this can be achieved with "nice" unix command. i don't know of a module that can do same from within perl. there is a module kstat which will give you current cpu load for processes, so you could parse that for your process id and do a few waits if high
