	IIRC NetBSD uses lazy swap allocation, so no longer requires the
	swap = 2 * ram rules of 'more traditional' unix.

	This leaves us with a simple 'more is better' rule :) - if you're
	running X on an 8mb machine you certainly want more than 16mb of
	swap!

	Use 'pstat -s' to check what your swap usage is, then load the
	machine up with as much as you'll ever want running and then some
	- if you're more than 2/3 of memory+swap used,  start thinking
	about adding more. (Be warned, NetBSD handles totally running out
	of memory _very_ poorly :)
