basically you're right. except that, the signal system in its current
form (and the type system with all its readily-boxed-magic ;) don't
know about passing value types by reference, which gets us all that
demand-copying mess.
we had some proposals for using additional GtkType flags to indicate
value-type references, but basically they were put down because they
didn't scale too well. i'm still somewhat uncertain as to what the best
approach here is... ;(
