On the Windows side I do not know, because I am still at NT4.0, but on the Mac Mathematica is capable to squeeze every bit of available memory out of the system. I observed many times that on a 640MB iBook The OS leaves about 495M for programs after boot. After long running Mathematica sessions I see in top sometimes 595M free ram when I start with a fresh kernel, that is Mathematica was forcing the OS to give up memory and to retreat back to the very basics. Now the side effect of it is that when I collect too much data and the kernel crashes by overstepping the 2G limit in virtual memory, then the OS has a hard time to recover. Many times in that situation I am unable to Quit or Force Quit Mathematica. If I am able to quit from Mathematica, then the OS reports just very meager amount of available memory - from 6MB to 250MB - , so I have to restart the machine anyway. I observed this with all the big cats {J,P,T}, so either something is fundamentally wrong how Mac OS X handles memory, or Mathematica does not comply with the rules.
