 Hmm, this is still pretty bad then as plenty of cleanup code (at least
dtor of wxApp and also dtors of all the global objects) is still not being
executed. I wonder if we can work around this by creating a dummy window in
wxApp::OnEndSession() (not a wxWindow as it would be destroyed too, but
just call ::CreateWindow())? If this fails (because I can imagine Windows
refusing to create windows during shutdown) we'd have to somehow avoid the
destruction of the existing windows, e.g. maybe by setting their m_hWnd
member to NULL from OnEndSession().

 But before embarking on this, could you please test if the simple solution
of calling CreateWindow() works by chance?

 Thanks again for your testing!
