At the time a task was assigned to you it doesn't need to be in deadline-trouble, but downloading the files neccessary to run the task isn't instantaneous. In case of download-problems it can take many hours, and even days, before all files are downloaded, and by the time the files is downloaded the task can be in deadline-trouble. Also, in case a project "needs" really fast turnaround-times, having the ability to start crunching immediately after the files is downloaded is needed. So keeping the checks on file-downloads is needed, and this shouldn't be a big problem. But I don't see any good reasons for re-calculating every minute or something, once per hour should be adequate. -- "I make so many mistakes.
