That would violate the inlining principle, though.
An inlined generator is going to get all exceptions
regardless of what they inherit from.

Whereas that would mean a shared subiterator would
get prematurely finalized when closing the delegating
So there seems to be no choice about this -- we must
pass on all exceptions except GeneratorExit, and we
must *not* pass on GeneratorExit itself.
