Handing off the host in wc3 games

[Strilanc]

I've almost finished writing a bot which can host games in wc3. The last obstacle comes at the very end: when players finish loading and enter the map. The bots responsibilities end there, and so I want it to exit graciously.

The problem is all the strategies I've tried for disconnecting end up killing the game (players are sent straight to the score screen). My fear is that I will need to send something different for every map.

Does anyone have any experience with this?
