I looked around but haven't found a definitive answer to this on the
mailing list archives -- how does SEDF handle oversubscription? I'm
not using weights at all -- just period/slice specifications for each
domain. So what happens if a user tries to give a specification where
sum(period/slice over all domains) > 1?

Looking at the code it seems that SEDF just *assumes* that the
specification will be valid. Is that correct? Does anyone have a
handle on how the scheduler will behave if an invalid spec is given? I
guess I could just try for myself....
