Using HMT (has_many :through) rather than HABTM will make your whole
problem go away, with no need for worrying about threading, object
context, etc. (At least, any more than usual!)

Try using an association table, to represent a given member's
membership (hey, sounds like a good class name there!) in a group.
That's where you can put info like whether they're current on their
dues *for that group*, when they joined *that group*, etc. etc. etc.
