What bothers me with the API as it is today is that I have call
enter/exit, I would find it more easy to work with an API like:
-------8<-------
WaitCondition c = new WaitCondition();
Dialog d = new Dialog() {
public void onClose() {
c.release();
}
}
Platform.spinNestedEventLoop(c);
------->8-------
