Keeping a reference to the object in global variable $foo is one way to stop
it frm being garbage collected.

A local variable is fine, as long as it doesn't drop out of scope: e.g.

foo = server.game
DRb.start_service($uri, foo)
DRb.thread.join # program waits here

drb itself holds a referent to this, the 'front', object - so i don't think
that'll help too much. i'm guessing the game returns result objects of some
type which are recycled in the server while the client tries to re-use them.

cheers.

Thanks guys. I'll keep these tips in mind while I keep digging through my code, trying to find if I let go of a reference somewhere.
