To make it clear, even though it would be incomplete, a partial implementation of os.kill(...) for Windows would be very useful and provide some level of compatibility with applications that use os.kill (so even if os.kill(...) duplicates functionality in other modules - although that was disputed - it should be provided for compatibility reasons).

An implementation similar to the IronPython one is probably the best that can be managed and would still be useful: accepting only signal.SIGINT and signal.SIGBREAK and first trying Kernel32.GenerateConsoleCtrlEvent, falling back to killing the process.
