[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.
