+ * This routine used to send a SIGINT (^C interrupt) to gnushogi to awaken it
  * if it might be busy thinking on our time.  This normally isn't needed,
  * but is useful on systems where the FIONREAD ioctl doesn't work since
  * on those systems the gnushogi feature that lets you interrupt its thinking
  * just by typing a command does not work.
