Every cable modem I have had suffered from some form of bufferbloat. In short it's not TCP's fault that your head shot packet sat in a cable modem's buffer for 5 seconds before being sent to the server.

Normally all long lived connections have some kind of TCP keep alive to them. When the TCP keep alive fails, the connection dies, and it's up to the application to restart the TCP connection. The proxy can send these out as well.
