Technically, in the release kDebug will print nothing, since it's only 
debugging :-)

Please make sure that calls to kWarning, kError and kFatal are cleaned up. 
Those show in the output.

Also, through some ifdef magic, kDebug will not even be executed when 
compiled in release mode. So please be careful with calls with 
side-effects, since they will not be executed in the first place. The 
same goes for Q_ASSERT.

One final thing: I've been toying with the idea of an "extended debug 
output", which will print the program's name, PID, the function name, 
source file and line number. That would make k_funcinfo unnecessary, 
since all of that information is already included.

I know it's a PITA when you look at your ~/.xsession-errors and see:
	QObject: unexpected null object
and you have no idea which program that might be coming from!
