There is race condition in the remote client attach logic. Because the resize api call was handled in an extra goroutine the container was started before the resize call happend. To fix this we have to call resize in the same goroutine as attach. When the first resize is done start a goroutine to listen on SIGWINCH in the background and resize again if the signal is received.
