It's seems really hard to justify even that much SWAPMETA.

That also seems like overkill for the vast majority of systems. -DG David Greenman Co-founder, The FreeBSD Project - http://www.freebsd.org President, TeraSolutions, Inc. - http://www.terasolutions.com Pave the road of life with opportunities.
