New submission from Christian Heimes: Guido has expressed [1] that he like to see IOCP support in the stdlib for the grant unified asyncore interface.
Quote from MSDN [2]: --- I/O completion ports provide an efficient threading model for processing multiple asynchronous I/O requests on a multiprocessor system. When a process creates an I/O completion port, the system creates an associated queue object for requests whose sole purpose is to service these requests. Processes that handle many concurrent asynchronous I/O requests can do so more quickly and efficiently by using I/O completion ports in conjunction with a pre-allocated a thread pool than by creating threads at the time they receive an I/O request. --- I've found a couple of interfaces to IOCP in Python projects. Twisted [3] has a Cython based interface to the IOCP API, Cogen [4] uses ctypes wrapper. I couldn't find IOCP support in Tornado. I favor a C implementation over ctypes. What's our attitude to Cython? Personally I like Cython and use it in several projects but I'm not sure if we shall use it in core development.
