/* The isProxyRunning shape (portless cli-utils): a request with the

 * after the idle period, destroy() tears the request down, and the
 * premature close surfaces as 'socket hang up' on 'error' before
 * 'close'. The never-answering server is a raw net server (the http
 * handler would answer); it closes on its socket's teardown. */
