Comment (by nbruin):

 YES! All tests pass for me too. I think the saying is "Mission
 Accomplished".

 Concerning speed effects:

 5.3b2 + (#715, #11521, #12215, #12313):
 {{{
 Total time for all tests: 1001.4 seconds
 Total time for all tests: 1002.6 seconds
 }}}

 plain 5.3b2:
 {{{
 Total time for all tests: 928.5 seconds
 Total time for all tests: 932.6 seconds
 }}}

 so people might want to profile their code every now and again to see if
 they are losing much time on construction/destruction of parents.

 I'll try to finalize the positive reviews on all these tickets and then
 hopefully these can be the first ones in on 5.4.
