NI is the niceness of a process, setting this high on a background process
that's going to run for a while, is a good thing to do, it'll make the
process take longer, but allows the other people (or you) to get on with
other stuff at the same time. Equally setting these negitive makes the
process run faster. The PRI field is the kernels internal priority for
that process, it's changed by the niceness. The kswapd process is a
kernel thread, and is niced (with a negitive value), because you want to
run it often (it's part of the new(er) swap stuff).
