Hmmm, Solaris 2.5.1, on the right hardware, supposedly lets you do a reboot
and restore the previous state. Natural extension of the power-save feature,
I guess, which will shut the system down, save its state and then restore it
on power up.
I'm not sure if that measns the mssage queues are persistant across reboots
but I imagine it increases the possibility.
