This shouldn't be a nofail - that is only for path that trigger from
destroy/error unwindow, which read dirty never does. The return code
has to be propogated.
It needs some more thought how to organize this.. only unfill_domains
needs this path, but it is shared with the error unwind paths and
cannot generally fail..
