Yes, and it really is splitting hairs, but I would caution against engaging in "premature optimization" <http://en.wikipedia.org/wiki/Optimization_(computer_science)#When_to_optimi ze>. I would, however, beg to differ on space vs time. CPU is "reclaimed" a million times per second or more; memory is only reclaimed on occasion (when explicitly freed). I would assert that generally, memory will have a longer persistence time than CPU usage--CPU spikes and falls often, but memory tends to stay constant (or gradually increase), generally speaking. It all boils down to user experience, in any case. Best, Keary Suska Esoteritech, Inc.
