Me likee. I think this looks like the right thing to do.
I didn't actually apply the patches, but just from reading them it
_looks_ to me like you do the migrate_disable() unconditionally, even

That sounds like it might be a good thing for debugging, but not
necessarily great in general.
Or am I misreading things?
