[Haskell-cafe] network-conduit proxy

[Alexander V Vershilov]

As it seems from code runTCPServer registers socket close 
and TCPClient runs it in bracket so all open resources should be
closed. It my last try I add 
  _ <- register $ killThread tId
after forking serverSrc $$ clientSink, to kill outter thread explicilty
otherwise it closes thread with error. 

> Is this the expected behaviour or are resources not being closed?

In 'strace' log it seems that both sockets is closed. So I think that 
computation is closed before reaching the end because src $$ sink closed
with error. If you want to run action at the end you can register it
