Just to chime in with my results. I don't know what version of perl sgifford was using, but I'm running perl 5.8.2 under Debian Linux. My results are:

My system seems to start with half a meg more RAM used (556K), but the percentage freed seems similar (42.7% for me vs. 43.7% for sgifford).

Does this imply a memory leak somewhere in perl, or that the garbage collector is caching the memory allocated for re-allocation later?
