Hi Rafael,

Just a gentle ping here. Could you please take a look at this
discussion?
I'd like to address some comments I received, especially on the subject
of making it reduce the state by one as opposed to going all the way to
0 to account for different hardware and how we can accomodate different
architectures in the implementation of that mechanism.

Before I send a v2 it'd be great to know your opinions on this and
whether I should still send it as a TEO patch or fork it into a separate
governor and make the changes there as both Doug and I seem to prefer.

Thank you in advance for you time,
Kajetan
