Hm, that's a point.

Well if you have a legitimate case for pre-empting the event loop with these
periodic regular short blocking moments (it seems you may), I think what you
want to do is overwrite FilterEvent on your App object. You can then make
that flag something you set on the app, and while it's true, returning False
(or True, I really don't know the differenced between telling wx 'Ok, I
processed this event you can ignore it' and 'Ok, I'm not going to process
this event and neither should you'). Otherwise, return -1.
