No, please leave it as-it. This information is the for the end-user not necessarily a developer. What you add is an information for someone who can read code. This information adds no value IMHO. This is enough as it is. Someone familiar with the scheduler can certainly remove the dependency while adding the needed code and replacing the current PI bits. Sebastian
