Ok, following on pipeline's idea, I wrote epause.

epause consists of a program that I wrote that returns the pid for the currently open window on your screen and a script that gets the state of the program (paused, running) and pauses it if running and vice versa.

Install the deb, reboot and run "gconftool-2 -s -t string /apps/osso/keybindings/global/epause escape" to activate. Replace "escape" with preferred key. Some keys like the fullscreen button and power button for example will not work (intentionally disabled in hildon-desktop). Pressing your key will run the program which will toggle the window's state.

If you have hw-screenshot installed, installing this will cause hw-screenshot not to work.

Don't forget - "frozen" apps still take up Memory (but are probably swapped out sooner or later if swapping is enabled - still, the memory usage is there).

For my part, I've taken this post as inspiration, and the next version of Tennix will save the current game automatically on quit and will allow to continue the game on next start.

I also think that while having a "general purpose" freezing/suspension utility, this should only be a temporary solution until all apps save and restore their state correctly.

Also, I think libosso already provides an API for putting apps to sleep and waking them later on - and IIRC this also makes them free up their used memory. You can see this in effect when you have many apps open, and some of them get that "zz" on top of their icon.

Is epause only for 810's? What would the key choices be on an N800?
