+ * [shogi-server] Improve timed-up detection.
+ Previously, the server checked if a game got timed up when a player
+ in turn sent no message for a certain amount of time mainly defined
+ by Default_Timeout. If the player sent keep alive frequently, the
+ timed-up detection could be quite delayed.
+ This issue has been addressed. The server now checks timed up with
+ keep alive received as well. Players are notified with TIME_UP not
+ long before games gets timed up.

+ * [shogi-server] Support a graceful shutdown.
+ A file named "STOP" in the base directory prevents the server from
+ starting new games including Floodgate matches.

+ To put a PID file such as /var/run/shogi-server/shogi-server.pid, if
+ directories do not exist, they will be created recursively.
