I think the socket-connect function in the SBCL backend
is incorrectly calling bind when creating a client stream
socket.
With the current code, when I create a lot of client stream
sockets on a Linux system, the bind call in socket-connect
eventually returns an error, address already in use. I don't
think the bind call is needed for the client end of stream
sockets.
The following patch appears to fix the problem for me.
