[Twisted-Python] socket is not closed when connection failed

[Yun Mao]

Hi everyone,

   I found that if a TCP connection is failed, e.g. UserTimeout or No route 
to host, connection refused, etc, i.e. when factory.ConnectionFailed is 
called, the socket is not properly cleaned up. i.e. socket.close() wasn't 
called. In this case, when I try to connect to many unreachable hosts, my 
file descriptor will finally be gone.

Could someone confirm me on this?  Thanks. I'm using twisted 1.3.0rc1
