I'm pretty sure they don't.  Closures don't keep a reference to the
calling frame, only to the appropriate cellvars.

Also note that whether a function is a closure has nothing to do with
whether it was defined by a lambda or a def statement.  In fact,
there's no difference between functions created by one vs. the other,
except that one has an interesting __name__ and the other does not.
