I don't think I understand that part of the code, although I have tried in the
past. I think the window handle patch (or a corrected patch for it, if I made a
mistake) is a must, because the parent must keep track of daughter windows and
releases resources correctly - the unpatched git code is just wrong (and as it
says, it has two FIXME's); secondly, the resources management must deal with
multiple help windows correctly (or just let it leak, rather than crash; and
wait for a proper fix for the leak later).

I haven't had a crash lately, since the local windows handle patch, but maybe I
am just not trying hard enough :-).
