Evaluate
(url-retrieve-synchronously "http://localhost:3333/foo")
As long as there's nothing running on that port, the function call
should return quickly, but it never completes.
On emacs-24, it works as expected.

If nothing answers then it will wait until TCP timeout.

But actually, the port is closed, so it should finish immediately with
"connection refused".

You didn't say how long "never" is.

Nothing above the default Ubuntu settings. Like I said, emacs-24 works
like expected.
Have you tried my example? Can you see the difference in behavior?
