Description

There are 2 potential problems:

1. The code that runs the scheduled tasks still accepts new tasks at the same time. So if you keep on scheduling new tasks continuously you could make the scheduler run tasks continuously without ever leaving to process any other events.
2. The code that accepts timeout events will keep on reading the same event batch until it is empty. So in this case too new tasks could prevent any other events being processed.
