[Mogobu The Fool]

I don't think it's a good idea because:
1. Most tables will be active when closed, making you lose some of the history (hands in progress will have a gap.)
2. Dead tables DO get removed by the Party system eventually, and this will selectively remove them. I think continues collection on games in progress is more valuable than one or two extra 'dead table' slots which would get scrapped soon anyway.

The burning question for #2 is: how long to finished tourney tables stay open? For limit, I know the big question is how long it has been since someone sat down for a moment. Otherwise, Party shuts down excess open tables until there is exactly one empty table available - but it makes sure there is always one empty table. This forces an "open all tables" strategy to have one empty table open.

Anyway, if the Party closes the tables in a reasonble period - 15 minutes, half hour - then a "close all" approach once an hour will save very little time (it will cut the table death time in half, on average) while disrupting live games frequently.
