 Recommended maximum number of elements for simple controls like wxChoice,
wxComboBox, wxListBox etc is a hundred entries, a couple of hundreds at
most. How can a user possibly select anything in a control with several
thousands of them?

 My first advice is to not use wxChoice for this. Maybe you could create
wxWindowUpdateLocker for it before clearing it (and maybe this could be
done by Clear() itself) and perhaps something else could be optimized in
its implementation (it might be deleting items one by one currently instead
of removing them all at once) but it was never supposed to be used with
such numbers of items anyhow.
