Yes, I confirm that the status of this series is pretty good, given the
goal we have for this scheduler.
In fact, both me, George and Meng agreed on considering this an
experimental feature, similarly to what we did for, ARM or PVH. With

the code already looks quite good.
If George wants to add anything...
