The memory number you need to worry about is peak usage. Perl hangs on to any memory the system gives it, and doesn't let go till the perl process ends. That has major importance for long-running processes, as with mod_perl and other daemons.

To expand further on this one, this is actually the operating system's fault. In *nix, a process address space can only be extended. I believe the same is true in Win32 systems, unless specialized APIs are used (which nobody uses anyway ;)
