I agree that is possible.
It at least meets the bar that every time this code path is executed
it will behave exactly the same way (we have spec'd things before
where we didn't even get this far, because of gc issues).
But it would be better to not have weird edge cases like this in
OTOH, it seems like showModalDialog() is just a sharp edge that is
likely to hurt you no matter what. Even with your proposal, unless you
carefully arranged things in preparation for showModalDialog(), you
could get stuck the same way.
