title: How to limit process memory utilization on Linux (e.g. using BSD::Resource)
body: <p>I'd like to limit the memory usage for my Perl script, running on a Linux system. I've been trying to use <a href="http://search.cpan.org/perldoc?BSD::Resource" rel="noreferrer">BSD::Resource</a>'s <code>setrlimit</code>, but have been having problems. I'd appreciate any pointers. Thank you.</p>
