+ * 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.

- * it move immediately when it is thinking about its own move; this could
- * be useful if we want to make Backward or ForceMoves work while gnushogi
- * is thinking.
+ * Now gnushogi periodically checks for user input without a need for
