It looks like we are after the same thing actually. :) Sorry for any confusion.
There are currently no provisions for actually sharing objects between
interpreters. In fact, initially the plan is basically to support
sharing copies of basic builtin immuntable types. The question of
refcounts comes in when we actually do share underlying data of
immutable objects (e.g. the buffer protocol).
What if an object is not going to be shared, but instead "moved" from
one subinterpreter to another? The first subinterpreter would no longer
have a reference to the object.
If the object's refcount is 1 and the object doesn't refer to any other
object, then copying would not be necessary.
