The first point doesn't stand true anymore. Lets wait for Mike's reply and
see his opinion.

And then the patches are so small and there are no objections against
them. I don't think getting them with the scheduler changes is that bad
of an idea. In worst case, what if he has to redesign his idea? The new
routines will stay without a caller then :)
