Might also want to to add the reference to the perlfaq3. And, maybe mark up this post into perlfaq3. You can build perl to use your OS malloc pretty easily. I'm told Perl malloc is faster and more cross-platform, I would be curious to know why. You can find out what version your perl is using by perl -V:usemymalloc. If it is n as it is usually then you will never give back memory to the OS. I'd like to know why on Debian it is off. I assume it is the default build option, but why if gnumalloc is present?
