Add option to not delete jsonpCallback upon execution

Description
When using jsonpCallback to set a static callback function, there should be the ability to have the function remain in scope and not garbage collected.
If I call the exact same jsonp request twice, the first jsonpCallback execution deletes itself, and then the second fails on being undefined.
Maybe there's also an option to cache the response of the first request, and on subsequent requests return the cached result instead of making the entire request and callback cycle?

I am not sure I understand this. Can you provide a test case?

So I think I've produced a test case for what I think orensol is getting at. The callback function isn't deleted, but the jsonp works fine the first time and then after that the callback function is called, but an error is thrown "Uncaught Error: NOT_FOUND_ERR: DOM Exception 8" -- jquery-1.4.3.min.js:135 I know the errors on minified js so its not as helpful, but this fiddle shows it happening. http://jsfiddle.net/vKHdg/

No, what you reproduced is the bug reported in #7418. Which is an exception when trying to remove a script tag in the internal callback handler
