Are you sure it's not just come user-code with memory leaks? I use
2.4.1 on an embeded system with no disks, therefore no swap. It does
large FFT arrays to make spectrum-analyzer pictures and it has never
seen any problems with VM, in fact never any problems that can be
blamed on the Operating System.

Try 2.4.1 and see if your problems go away. If not, you probably
have user-mode leakage.

Penguin : Linux version 2.4.1 on an i686 machine (799.53 BogoMips).

I was going to compile a list of innovations that could be
attributed to Microsoft. Once I realized that Ctrl-Alt-Del
was handled in the BIOS, I found that there aren't any.
