I've hit the same kind of problem before. Big task runs & eats all the memory. Later on, a login to the machine or existing shells are horribly slow until they get swapped back in.

However, swapoff/swapon only solves part of the problem - you still have binaries, libraries and other file-backed memory that were thrown out under the memory pressure and they won't be reloaded with the swapoff/swapon. Does anyone know how to force these kinds of things to be re-loaded before they are needed again?
