So so.. Perhaps you just need an application which runs (fork/exec) 
new programs, and also, open(/dev/input/event0, read_only) and reads
key events. If you find the proper pressed keys you can finish
your child process perhaps?

Thas is just an idea, because I did not want to talk about a complete
process manager like a window manager controls the windows on X,
just an easy way to control a bit the application on fb.

If you just need to end running applications perhaps you can
use the power button. One second button pressed finishes the
current application, longer power off.

This idea sounds very interesting as well, but you need to rebuild every
application against this lib yet.
