no....it's exactly the same.
We do not 'wait' for tasks at any stage. We first detect that there are tasks; 
and if there are tasks we ask user if he wants to clear them.

If user wants to clear them, we put the engine into maintenance mode, set a 
vdcoption value to 0 (meaning we tell the engine all running tasks are zombies 
and need to be cleaned), and wait indefinitely until all tasks are cleared, 
asking a user whether he still wants to wait each 20 seconds.

So clearing is waiting in our case.
