The problem with not doing a full set of builds in rawhide is that it 
significantly reduces the testing - both in terms of making sure that 
code still bilds, and in terms of making sure that we don't have 
unexpected functional regressions. Shortly before release is a really 
bad time to discover this. My impression is that the kernel team don't 
want that to be a possibility.

Yes, there's no fundamental reason that these builds need to occur in 
series. If koji had support for exploding builds out to multiple 
machines then things would work much better. Another alternative might 
be to investigate whether distcc is practical in this environment.
