SSL fix for flask dev server

sslfix.py

from SocketServer import TCPServer
from OpenSSL import SSL

def patch_shutdown_request():
    # Fix SocketServer's shutdown not working with pyopenssl
    def my_shutdown_request(self, request):
        """Called to shutdown and close an individual request."""
        try:
            #explicitly shutdown.  socket.close() merely releases
            #the socket and waits for GC to perform the actual close.
            try:
                request.shutdown(socket.SHUT_WR)
            except TypeError:
                # ssl sockets don't support an argument
                try:
                    request.shutdown()
                except SSL.Error:
                    pass
        except socket.error:
            pass # some platforms may raise ENOTCONN here
        self.close_request(request)
    TCPServer.shutdown_request = my_shutdown_request

This looks like it'll solve a problem I'm having, but Google hasn't helped me figure out how to APPLY this fix. Forgive me, I'm a sysadmin not a web dev so I'm mostly hacking at a Flask app written by someone else.

Where should I put a call to patch_shutdown_request()? Sometime before app.run()?

Works for me (the fix proposed on http://flask.pocoo.org/snippets/111/ didn't). Thanks a lot!
