Even 10 seconds seems rather long, doesn't it? You'd have to have an
awfully busy system to need to wait more than like 5 seconds for the
closing backend to get scheduled, and it'd be rather ugly to force
someone to wait 30 seconds just to find out that someone's still
connected to the database.
How about starting with 5 seconds and seeing if that takes care of
most situations?
