As I mentioned previously, this really doesn't work: if your program has a
bug and raises an unhandled exception, it will deadlock again (and probably
not even tell you what happened!). You could try to put handlers all over
the place, but that is an amazing pain and quite fragile.

I think you either have to use JEWL as it was intended (with modal dialogs
declared in subprograms; I can't think of any good reason to declare a modal
dialog in a package anyway: it can't live very long, since it prevents
everything else from working) or switch to a different GUI library. (I'm
partial to Claw, but any of them would work.)
