Delegating generators do not show always up in stack traces, such as inspect.stack(). The show up during the first delegation, but not thereafter. I have attached a patch. It alters the way the YIELD_FROM bytecode works; it loops back on itself. This ensures the delegator's frame is always in the trace. Unfortunately I started working on it before Benjamin fixed issue 14220 (rev 3357eac1ba62). By the nature of it, this patch necessarily fixes most of issue 14220, so I have just included the tests for issue 14220 in this patch as well. So in order to apply this, 3357eac1ba62 will have to be backed out. Sorry for the overlap.
