Well, I don't propose custom event loop. Loops with processEvents() (used in 
38 places in KDEPIM and used by me in Kexi), if properly used, is better than 
overlaping signal-slot sequences.

I am asking about this single case. What difference can you see between these?

1. proposed by me

	dosomething();
	qApp->processEvents(); //will perform some actions from the main loop
	dosomething();
	qApp->processEvents(); //will perform some actions from the main loop
	dosomething();
	qApp->processEvents(); //will perform some actions from the main loop
	dosomething();
	qApp->processEvents(); //will perform some actions from the main loop
	dosomething();
	qApp->processEvents(); //will perform some actions from the main loop
	...

2.
	QTimer::singleShot();
	// perform some actions from the main loop
	dosomething(); //executed by QTimer::singleShot
	QTimer::singleShot();
	// perform some actions from the main loop
	dosomething(); //executed by QTimer::singleShot
	QTimer::singleShot();
	// perform some actions from the main loop
	dosomething(); //executed by QTimer::singleShot
	QTimer::singleShot();
	// perform some actions from the main loop
	dosomething(); //executed by QTimer::singleShot
	...
