I do not think that is a better place as not every consumer of module_list
(and module_list_compute as the nested function) will need to use the
submodule caching API. So these consumers are not interested in possible
bugs in the submodule cache API nor do they want the performance hit
which comes from checking unrelated stuff in there.
As said, I only saw this bug when the cache was not initialized properly,
and then such a bug is to be expected. I'd rather remove it in a reroll.
