Good, that's what I did already. :)

So if I understand it correctly, at least reactor.callFromThread (and
callLater?) are thread safe in this case?

I'm not sure I understand. Do you mean that a reactor.callFromThread won't
do to, say, insert text into a text control, and I should use wx.CallAfter
instead, even in your unthreaded recipe?
