write state to swap for multi-os boot

[ctodd at chrismiller.com]

Has anyone considered or accomplished allowing FreeBSD to write it's
current state (including window manager, windows, etc) to swap and
allowing a subsequent reload of the system to last state? This would be
sort of like the sleep mode of a laptop, but would allow the user to boot
into another OS (like Winblows) briefly and then resume their FreeBSD
system state. I'd love to use FreeBSD as my primary desktop, but there may
be times where I'll need to boot into Windows for apps that don't run
under Wine. Since I tend to have a lot of application windows open, it's a
PITA to have to reload everything on boot. Thoughts?
