Yep you right.
But suspend mode will be totally useless on the computer on which no programs
are running.
The sence of suspend mode to put the computer to sleep with all running
programs, and then wake up and that everything continues to work.

Anyway, I see that in swap there was enough space for unloading the full size
of RAM.
