This is the old "show dialog" problem. Basically, swing and the
AWT in general are really stupid, they block the thread that
shows a dialog. The "fix" is to call the show command with the
unsupported::jdetachcall command. It will spawn another thread
that will block in the dialog show call. This might seem
like a hack, but it is the same one the AWT uses.
