OK, that makes sense.  This situation would clearly be a bug in the
module loader.  Maybe it would be worth making ES robust against such
bugs though.

This wasn't obvious to me from reading the spec, although there is an
assertion in ModuleEvaluation that ModuleDeclarationInstantation has
completed successfully first that would be invalidated in this case.
