Thanks Tim! I'm not sure who should review the patch, but it's not me. :-) I've verified that the patch stops the example program from segfaulting on OSX, and I assume you've verified it on Windows -- that's good enough for me. We don't see this happening much in asyncio, so it's a likely story that the demo program happens to arrange for the refcounts to be just so.
