	NetBSD does not preallocate swap (which has its own problems when
	you run out of virtual memory), so you do not _need_ any swap at all
	(a 64Mb ram machine with no swap would be a better box than a 32mb ram 
	with 32mb swap :), but its obviously sensible to allocate some

	Work out what you expect your max virtual memory usage would be,
	then double it (paranoia) and subtract your ram - thats your swap
	size :)

	FYI: 64Mb *BSD sparc with 16 users:

	(muon ~)14# pstat -s
	Device      1K-blocks     Used    Avail Capacity  Type
	/dev/sd0b      103500     1108   102392     1%    Interleaved

	(damn, thats over a megabyte of swap used :)
