      Issue
      -TCP and UDP sockets are not well supporte
      -Blocking sockets on the main thread not supported

      Solution: 
      -Tunnel TCP and UDP sockets over WebSockify, using functionality provided by Emscripten.
      -Event dispatcher socket notifier support for async (nonblocking) sockets on the main thread
      -Use asyncify for blocking sockets on the main thread.
      -Local socket proxy towards the HTTP server
