This is a confusing name--it seems like it might mean, "perform an xhr GET request". What it really means is, `getRequestInfo` or something, the old version called this `reqInfo`.

As far as I can tell, this function is only called once, at line 138 of this file.

How about we just inline it, then we can rename the awkward `makeRequest` to `request` or `XHRRequest` or something.
