Is there any way to detect / avoid leaks on this separate refcounting

Antoine Pitrou <pitrou [at] free> added the comment:

This patch integrates the dictkeys' refcounting into the refcount checking framework. Seems to work ok, but it would be better if someone more acquainted with the code could confirm it.

Change insertdict to follow normal (non-stealing) ref-counting behaviour which fixes possible leakage.

Patch attached.
