Sorry; I didn't notice the `with-timeout' thing at all.

Yes, the `with-timeout' is the reason the buffer isn't killed.  Because
it'll just return nil when timing out, and there's no way to get at the
buffer url.el created.

For reasons like this, `with-timeout' isn't recommended.
`url-retrieve-synchronously' should have a timeout parameter.  Feel free
to submit that as a wishlist bug report with `M-x report-emacs-bug'.
