|Socket.close calls shutdown twice on the same file descriptor 

Ruby 1.8 creates two FILE* streams on a socket to implement
bidirectional communication.  Two calls to close(2) is a side effect.
Since it shouldn't do any harm, we don't consider it a bug.  Tell us
if it would cause any trouble (other than one useless system call, and
a failure in strace log).
