[Python-Dev] Fixing send()

I've got a possible patch for the send() problem. I'd like review of the patch and the related issues before I apply it. I'd also like more guidance regarding the suitability of this patch for the 2.1.2 bugfix release. (It fixes a real bug, but can sometime lead to different behavior, and adds a new interpretation of the absence of an optional argument, which can be considered a feature.) http://sf.net/tracker/?group_id=5470&atid=305470&func=detail&aid=474307 --Guido van Rossum (home page: http://www.python.org/~guido/)
