It appears to be a function of time, if an open program is not used for a while it gets swapped to disk even if no other program is requesting memory. I suppose the kernel is anticipating -- this process hasn't been used for a while, swap it out, be ready for a new process. I would try to run without swap but editing the odd large graphic file requires it. The newer the kernel is the more I notice this. It didn't happen with kernel 0.99 pl 14 :) Thanks R.
