si/so is normally 0 (when the machine is idle). During menu manipulation,
it's... well, nothing happens now; the machine has been unused since I
checked it last. But from what I recall, 20-80 or so. Is that in units
of 4k pages/sec, or kB/s, or pages/(vmstat refresh period) or what?

Looks like I can reduce VMware's memory allocation to about 500M (450 if I
can tolerate some swapping), and I need some more RAM. I think reducing
it will reduce VMware's misconception, thinking what is 'real' RAM is in
fact swapped out by the host. Instead, it would swap it out itself, and
_know_ that it is swapped out.
There's a cron job that runs at 5am that backs up one hard drive onto
another identical one (the second is spun down the rest of the time), so
it uses a lot of disk cache, although in this case the data won't be used
again.
