What I did is a revert the refactorings while keeping the affinity API -
we can safely postpone them until the next release without loss of
functionality. But that's on top of my testing tree so it has unrelated
stuff as well. I'm rather confident they aren't fixing the issues but
I'll prepare a bugfix-only tree now for testing.
