Dispatch arrived gen_udp messages

[Edward Wang]

I gen_udp:open/1 a udp socket in one process, gen_udp:send/4 some packets in
another using that socket. It seems process that opens the socket gets
arrived udp messages. Is there a way to get these udp messages dispatched to
the process send them? Of course I can dispatch them myself. I just wonder
if there's build-in mechanism to do the same.
