> 2. Python's runtime is completely and utterly incapable of threading. Threading being almost essential to any decent user interface, this whole idea falls flat This simply isn't true. Python has the GIL, but that doesn't stop it from making use of threads for IO or CPU bound tasks that release the GIL (using extension modules). There are lots of libraries for multi-threaded IO in Python (e.g., gevent, Twisted, Tornado, asyncio), and, not surprisingly, they are very widely used for web programming.
