Do you allow oversubscription with EDF? It would seem so based on these
results. Would it maybe make sense to disallow oversubscription, or
make it an option?

If you have massive oversubscription with EDF, what is the design
intent? Do you try to meet the goals on as many tasks as possible,
while the oversubscribed tasks get nothing?
