Sorry for talking with myself, but I think that in fact it doesn't
matter whether there's a non-modal or modal dialog. Single-threaded,
asynchronous data reception and visualization (inside a main window) can
still be accomplished, since a modal dialog should not block input
sources or idle or timeout handlers of a main loop, if I'm not mistaken.
