In this case, modules are not even loaded so surely they can't be
called. The fact that one could call module_invoke() does not imply that
all modules are available.
The current best practice for injecting content into <HEAD> tag is to
use hook_menu(!$may_cache). using init is a bad idea. The developer docs
state this but unfortuantely the vrsion which shows at drupaldocs.org is
so old that it omits this info. I have mailed Kjartan about this.
