You might want to compare with Bart's patch for the same thing, http://www.winehq.org/pipermail/wine-patches/2011-April/100570.html
Bart asked for comments on it, but didn't get much feedback: http://www.winehq.org/pipermail/wine-devel/2011-May/090029.html My guess is changes like this are really hard to get in unless you can get Alexandre's full attention somehow. Maybe if it was demonstrated to find interesting bugs in wine...
