I also made a couple of tweaks to how you shutdown winamp - sending multiple WM_CLOSE messages can cause apps to crash. I believe that's why I'm frequently seeing winamp crashing at RR shutdown with recent builds. I have yet to see it with my changes but I haven't really spent long enough using it to be certain. Regardless, I think those couple of changes are a good idea - just send one WM_CLOSE and then do the wait for it to take effect.
