Most of the details are available in first patch. Second one is there to ensure
we'll have a useful error message if start_exclusive is called from cpu_exec
again.

I'm a bit puzzled that we never triggered this hang before. Is there something
wrong with the potential slow path for ptw_setl, or is it simply very uncommon?
