Heh, don't ask for something "silly" then :-) You might want to play around a 
bit with kdelibs/kdecore/tests/kprocesstest.cpp, you can compile it by typing 
"make kprocesstest" in that directory. E.g. replace the line with:
	p3 << "ls" << "-l";
with your program and see what happens.

You might want to add some etra checking of the return value of 'start(...)' 
and listen for processExited(...) and check exitStatus() when that happens.

Cheers,
Waldo
