Provide a mechanism to load any random JS file via dojo.require()-ish syntax.

Why would we want to do such a thing, you might ask?

Well, the short answer is that Firefox hates pages that have more than one script block (inline is worse than tag) that contains pre-onLoad XHR.  So, this allows us to pull the actual loading of JS from the same domain as the page into an inline block.  This allows us to eliminate the WSOD on FF by pulling all (dangerous) JS into a single, final inline block, after which we don't care if the DOMContentLoaded event fires -- that's when it should fire, structurally -- but in FF it may fire for a different reason (bug) than it should (fell of the end of the page in the rendering engine).
