I was sick and tired of having to scroll through a raw copy of jQuery everytime I wanted to view a method's implementation... so I decided to have a go at creating a faster, more usable interface which would allow me to quickly traverse each method's source. It's dead simple. Type in a jQuery method name (then wait a bit) and the corresponding source will show up.

Now, any time you modify myRequestHandler.js, the above code will notice and replace the local requestHandler with the new code. Any existing requests will continue to use the old code, while any new incoming requests will use the new code. All without shutting down the server, bouncing any requests, prematurely killing any requests, or even relying on an intelligent load balancer.
