It's a bit questionable if we should cache scripts when loading was ok but
evaluating scripts had exceptions (spec issue?)

[michaeln, 2014/05/13 22:41:11]

Spec issue is right, this is a question for the registration job to answer. Is
the registration "committed" or not in that case?

|is_eval_complete_| is always true here.

[michaeln, 2014/05/13 22:41:11]

Done.
