Some upstream peers (e.g. QQ Mail's rate-limiter) silently hold a proxied TCP connection open indefinitely — sending no data, FIN, or RST — rather than cleanly refusing. Without some kind of timeout management, the two file descriptors for such a session remain open for the lifetime of the process, slowly exhausting the kernel's file-descriptor table and occupying proxy-server worker slots. This commit configures kernel level keepalive options with reasonable defaults to detect and close out this class of connection.
