8.39: How do I set CPU limits?

(contributed by Xho)

Use the "BSD::Resource" module from CPAN. As an example:

use BSD::Resource;
setrlimit(RLIMIT_CPU,10,20) or die $!;

This sets the soft and hard limits to 10 and 20 seconds, respectively.
After 10 seconds of time spent running on the CPU (not "wall" time), the
process will be sent a signal (XCPU on some systems) which, if not
trapped, will cause the process to terminate. If that signal is trapped,
then after 10 more seconds (20 seconds in total) the process will be
killed with a non-trappable signal.

See the "BSD::Resource" and your systems documentation for the gory

are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.
