 I just merged your temporary fix, Thierry, so the segfault is supposed
 to be gone. CCing Marc-Antoine and Cyril on this. In the mean time, guys,
 please don't add code after txn.close(), as it more or less expects to be
 final. In all your examples it was already fine, but if we manage to enforce
 it to be final, you'll get less surprizes later :-)
 
 Thanks,

 Hello,
 
 I'm trying to make HAProxy work as a router for certain requests. What I
 have is a very simple configuration which sends every tcp request to a
 Lua script. The script then is responsible to parse the request, see for
 which server it is and forward it there. It then waits for a response
 and forwards the response back to the requester.
 
 The code is kind of the following:
 
 function hello(txn)
 local request_msg = txn.req:dup()
 
 local tsm_sock = core.tcp()
 
 tsm_sock:connect(127.0.0.1, )
 
 local res = tsm_sock:send(request_msg)
 
 local response = tsm_sock:receive('*l')
 
 txn.res:send(response)
 txn:close()
 end
 
 The problem is that in versions 1.6-dev2 and 1.6-dev3, socket.connect 
 timeouts.
 The server to which we connect is a simple echo server. I've telneted numerous
 times directly to it and experienced no problems, so I assume that the error 
 ain't
 there. Also, on version 1.6-dev1, the connect doesn't timeout and everything 
 works 
 okay.
 
 What could be the issue?
 
 Thanks!
