As far as I know, they do.
To be clear, the strong cache there is supposed to make things ''not
worse'' for Singular rings. It's simply reinstating strong references that
#715+#11521 removes (that's the idea at least), until we figure out how to
properly collaborate with singular's (lack of) ref counting.
As it stands, this should make things ''better'' for many other parents.
At this point the most important bit is to get to a point where parent
deallocation code actually does get excercised.
