[excellent analysis elided] I think the conclusion here is that using the file-name-handler-alist stuff for this is the absolutely pessimal way to implement `browse-url-emacs'. It should be pretty easy to rewrite browse-url-emacs to just call `url-retrieve-synchronously' explicitly, and then display the resulting data -- and it should be much, much faster.
