On the 256MB Pi, a small (128MB) swap file might prevent out of memory (OOM) situations. On a 512MB Pi the benefits are much less pronounced as OOM situations are extremely rare.

It's handy to have if you're in a pinch, as you might be with a 256MB Pi, but memory optimisations are the best solution and great strides have been made in that area over the last few months.
