Lately every day when I come home from work I notice a handful of applications taking up a surprisingly high amount of Real Memory. 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?

Note: Mac OS X 10.4.9 seems to fix the bug described here.
pmTool, the process run by Activity Monitor to actually collect stats, appears to leak memory. If I leave Activity Monitor running for a good period of time, when I check up on it
pmTool is often using over 100MiB of Real Memory.
I just checked my laptop,
pmTool was using over 100MiB of Real Memory. Right now on my desktop it’s using 41MiB of Real Memory, but I don’t remember how long it’s been running for. I also believe a good deal of memory is currently paged out.
After checking up on it,
pmTool on my desktop has a Private Memory size of 91MiB.
