Anyone know what I should believe? Sar's pgpgin/s and pgpgout/s tell me
that it is paging in/out from/to disk. Yet pswpin/s and pswpout/s are
both 0. Swapping and paging are the same thing I believe. pgpgin/out
refer to paging, pswpin/out refer to swapping. So I for one am confused.

I guess I could dig through the source but I figured someone might have
encountered this disrepency in the past.
