Its possible this leaks in IE, but its also possible that only happens if you "leak" references to event handlers. I believe we correctly clean these up.

Does the JSONP technique just add <script /> elements to the DOM? Adding and removing the <script /> elements seems to leak memory in IE.

It was designed with the ability to make arbitrary requests at arbitrary times. There's no guarantee about what order the responses will come in, but with a five second interval they will probably come in the right order, and its also trivial to manage this yourself.<br><br>I don't have any specifics about browser memory characteristics using JSONP versus a regular xml http request, but I would image they are fairly similar.

I wanted to comment about using CPJSONPConnection class for accomplishing cross domain communications. I've built a chat web app that's loaded within one domain but communicates with a subdomain. I've implemented a polling messaging technique to inform the user of any messages that they've received. Have you tested using the CPJSONPConnection class in a situation where the app has to make multiple requests (5 seconds apart)? Do you have any ideas about the browser memory usage when using the <script /> tag technique? Nice job.
