OK. I hope I responded in the other email in a more intelligent 
fashion.

Not sure about that. Its rarely used and the more general cpu alloc stuff 
can be used in lots of places as evident by the rest of the patchset. But 
lets leave it if its important for some reason.

Yes thanks. We are mostly on the same wavelength.
