 *  cannot be used, or a socket that cannot be opened, is logged under
 *  DEBUG and the run goes on without attach: a program must never fail,
 *  or print, because it cannot be debugged. When the socket fails the
 *  record is removed with it, so the listing shows only programs a
 *  debugger can reach. Until this change the socket was opened on
 *  SIGUSR2, and nodemon, which restarts a child with that signal, left
 *  the program running with its debugger open instead. */
