You can have a parent process do the binding and then share the listen
socket with child processes. Or, you can on most OSes set the binding
policy to allow multiple processes to listen to the same socket.

In all of these cases, you should use MHD_OPTION_LISTEN_SOCKET to pass a
pre-bound socket to MHD, so that you can open, bind, set options and
share the socket, instead of letting MHD open a fresh listen socket.
