Comment (by nbruin):
Apart from fixing `len(recently_created)` at compile-time this may well be
a good idea. Main objections:
- It will make debugging that much harder. Given that doctests are small,
the parent deletion code will hardly be exercised.
- Do we have good use-cases that show clear benefit from this approach?
Given that the frequency of garbage collection in python is rather low,
I'd expect that parents will relatively often still be around if they are
required soon after deletion.
