Process resource control is something completely done by the operating system. So your mileage may vary.
You can program yourself a form of control by monitoring
the system and kill your childs when they got too greedy.
in reply to How to limit resources ?
There are several modules on CPAN for process monitoring/control. Do a CPAN search on 'proces' than 'proc' to find one that fits your OS.
"We are not alone"(FZ)
Update: Did that search on CPAN and found:
Proc::ProcessTable and Win32::Process. There are modules for Solaris and Mac as well.
