that's not really correct.  basically, what it does is allocate a
large chunk of memory, and use it as a file system.

Yes, it'll eat some of your swap space, but its space doesn't decrease
as your swap usage increases.  it more or less takes a constant
chunk of swap (and memory, depending on access...) and uses it.

umm, on lamp, i think we use a line like:

/dev/sd0b	/tmp	mfs	rw,-size=16384

in /etc/fstab.
