Replying to [comment:74 SimonKing]:
> 1. Find out why apparently not all actions are registered in the parent
(because then we would have a strong reference as long as at least the
domain is alive).
That's why:
{{{
sage: search_src("register_action")
structure/parent.pyx:1698: self.register_action(action)
structure/parent.pyx:1791: cpdef register_action(self, action):
structure/parent.pyx:1841: sage: R.register_action(act)
structure/parent.pxd:29: cpdef register_action(self, action)
}}}
So, simply register action isn't used at all - which makes me think why
some actions ''are'' stored in the parent.
