This turned out to be worlds of pain and I ended up redoing the way
part of runqueue works, for the better as it turns out as the code is
much simpler. Its given me quite a headache trying to digure out how it
was breaking and reproducing it.

The new code is in master-next and I'm trying it on the autobuilder. it
shouldn't have the above problem any more, what other issues I may have
added remains to be seen!

Cheers,

Richard
