No, like i said, that's not how I'd do it (I would make `this` explicit
and avoid all those issues), but that last patch /will/ work.

The problem is with *pointers* inside an object that point to that same
object. 'Pointers' includes delegates (those contain a context pointer).
You're not storing any pointers, so it's ok. It was my first quick "fix",
which attempted to update the context pointer in the postblit, that was
wrong.
