Actually, we were talking about the previous one, which (if I got it
well) didn't include reservations, and that's why we were wondering how
to integrate it in the scheduler (which _is_ reservation based).

Now that this one is out, going for it simply solves all our issues,
also considering that it says something very similar to what we (Pisa
guys :-D) are familiar with, since we investigated this stuff too
sometime ago (actually, Luca did).

I think it really should be... Actually, I'm under the impression that
we don't even need variance/std-dev of the execution time to be part of
the interface, do we?

Yes, as I said, this was because we were looking at first paper. Now we
got it, thanks a lot for clarifying! :-)

A lot, thanks again.
