In general the linux kernel's VM subsystem doesn't freeup no longer used pages in the way you might think. Mostly that's left up to the applications in question and subsequently the system libraries. In the case of swap for certain, things that are paged into swap that are no longer used are not paged out (IIRC) but the dirty buffers are marked as "free" so they may be used by something else. Go through the kernel archives looking for stuff about the VM related to the particular kernels you're refering to for further information.
