Comment (by SimonKing):
With vanilla public/sage-git/master, I find that `sage -t --all` results
in 1083022 calls to `Parent.__init__`, while with the branch from here it
is called 1129534 times.
Hence, there ''is'' an increase in the number of parents being created. No
surprise, since this ticket is about making parents garbage collectable in
some situations.
Nevertheless, it might make sense to see whether some types of parents
show a particularly strong increase, so that we can then decide whether we
should have some stronger cache for these types.
