These apps tend to be Quicksilver, Safari, iScrobbler, NetNewsWire, and GrowlHelperApp. Every day I end up quitting at least 3 apps to free up some memory and it happens all over again.

Right now Quicksilver is using roughly 235MB of Real Memory. Running vmmap on it tells me that almost all of that memory is in the malloc zone, and the vast majority of that malloced memory are freed blocks. So my question is why are my multitudes of freed MALLOC_TINY pages not being reclaimed by the system?
