PNGFiles load from stream doesn't work with TCPSocket

General Usage
1

I have a simple server that just serves up a raw PNG file any client that connects. In Julia I wrote the following function to attempt to load that image.

function ReadTeensyImage(server)
    sock = Sockets.connect(server,555)
    img = load(sock)
    close(sock)
    return img
end

Unfortunately I get the error below. Ideally I would think the PNG library should default to assuming that the IO object passed in has no lock function. But it appear to do the opposite. It assumes the object has a lock function unless it is a specific type that does not.

Is there some way I can wrap the TCPSocket in a IOStream to work around this?
