The UnixStream has an FD leakage problem.

The UnixStream has an FD leakage problem.

When the socket_addr error occurs, the socket is not released.

    let socket = new_socket(libc::AF_UNIX, libc::SOCK_STREAM)?;
    let (sockaddr, socklen) = socket_addr(path)?;
    let sockaddr = &sockaddr as *const libc::sockaddr_un as *const libc::sockaddr;

   syscall!(ioctlsocket(socket, FIONBIO, &mut 1), PartialEq::ne, 0).map(|_| socket as SOCKET)

Yup, good find.

I imagine most UDS implementations are the same. I'll take a look at them

I took a look and found two places. Why not follow the standard library? When the socket is created, it returns a wrapper object, which is released in the drop method of the object.
