Ah good, if it's so easy to enable the elision, this kind of change looks safe
to me. But __pop_heap doesn't seem so straightforward to tweak, we also changed
a bit the interfaces. Marc can you submit a complete patch? Otherwise, so close
to the branch for 4.7.0 I'm not sure I will be able to work on this, or maybe
you can coordinate with Jon.
