TypeError: Cannot serialize socket object
---------------------------------------

I am trying to send a ssl wrapped socket object (server side) into a pipe to another process using multiprocessing.

Btw, without ssl_wrap it works.

Basically this:

newsocket, fromaddr = self.socket.accept()

connstream = ssl.wrap_socket(newsocket, server_side=True, certfile=self.certfile, keyfile=self.keyfile)

pipe = multiprocessing.Pipe()
proc = multiprocessing.Process(target=proc_run, args=(pipe[0],), daemon=False)
proc.start()

#Error here
pipe[1].send((connstream, fromaddr))

I am sorry if this is intentional.
