Ignore throw $break in Chrome JavaScript debugger

I'm using Prototype in a web app, and I'd like to break when exceptions are thrown (including handled ones). However, I don't want to break on exception used for flow control, specifically the throw $break pattern used in Prototype's each implementation.

function detect(iterator, context) {
  var r开发者_开发问答esult;
  this.each(function(value, index) {
    if (iterator.call(context, value, index)) {
      result = value;
      throw $break; // I want to ignore this one
    }
  });
  return result;
}

Does anyone know how to get Chrome's debugger to ignore specific exceptions? Or to get it to ignore exceptions thrown from specific lines? Or even to get it to not break in specific files?

I'm fairly certain there is no such feature. The documentation, which seems fairly complete, doesn't mention it. Also, the Chrome Developer Tool uses the Remote Debugging protocol, whose Debugger.setPauseOnExceptions command does not have a "file" parameter. That said, I have not grokked the source code.

Getting Chrome's debugger to ignore specific exceptions or files would also help when working with jQuery. It catches and re-throws any exception in an event callback (search for "resolveWith"), making the message in the console essentially useless. jQuery throws and catches exceptions internally all the time, so breaking on all exceptions produces too much noise.
