No, I don't think there is. When you use JSONP or other script-tag
techniques, jQuery creates the script tag DOM element, but I don't think it
can get any response if the script fails to load. Whatever happens, happens.
It's technically possible to simulate a timeout by wrapping the JSONP
callback function, wait for the timeout period, and then check to see if the
callback function set some known value. If it hasn't set this value after
the defined timeout interval, destroy the callback function and script tag,
and trigger a timeout. I built a custom JSONP function that does this since
jQuery didn't back when I needed it. I've been meaning to look at core and
contribute a patch to simulate timeouts for JSONP calls, but the code is
pretty wacky so I haven't had time to parse it and understand how a patch
like this might work. Not sure if the state of affairs has changed since
1.1.2...
