I can't think of a single usecase where it would be appropriate to load a
module twice ... It would be effectively the same as loading YUI, or Dojo, or
jQuery twice, Once it is there the first time there's no need to load it again,
the code is already there.
If you are simply trying to place a panel in multiple places on the page, that
can be done from the single invocation of your module, look for the container
elements in the DOM and add your panel (widgets)
RootPanel.get("contianer1").add(myStuff);
RootPanel.get("container2").add(anotherInstanceOfMyStuff);
