If JavaScript stalls because of an endless loop or other clever thing that I as the developper inadvertently did that somehow bypasses the execution limits of the webkit js engine, then I cannot open the debugger to find out what is causing this. (Since the debugger and the js engine all run in process even to the main event loop.

So in effect the whole browser is stopped.

This is ok for webpages and small js apps that are not so complicated. When developing huge applications to be run in the browser however this is not anymore ok.

I simply need the ability to stop the programm at any stage - no matter how misbehaving it is - and inspect what it is doing and why it is behaving the way it does.
