Not new, nothing has changed in since gtkosxapplication replaced gtk-mac-menu.

I guess that would be because the main thread has passed control to a CFRunLoop -- effectively the same
as a modal dialog. That's unavoidable, because all GUI events have to take place in the same thread. If your
events are time-critical, then you'll need to put them in another thread with its own gmainloop.
