Enabling & tuning a swap file [Angstrom]

Has anyone set up swapping with a small swap file on Angstrom?

And/or been through the /proc/sys/vm configuration with a fine-toothed comb?

I’m running a collection of pretty demanding apps, and they seem to eventually take down the system.

I want to configure a little swap space, and have confidence that my swap (or other!) configuration will just crash the app before the app can crowd, destabilize or otherwise perturb the kernel.

Pointers to what’s already been done, or helps diagnosing problems of this nature, greatly appreciated.

Thanks in Advance,
