Presently, #715 + #11521 help not permanently keeping parent in memory. In
the process we uncovered a hard-but-consistently triggerable problem with
the collection of `MPolynomialRing_libsingular`. We have only observed the
problem on `bsd.math.washington.edu`, MacOSX 10.6 on x86_64.
The present work-around is to permanently store references to these upon
creation, thus preventing collection. It would be nice if we could
properly solve the problem (or at least establish that the problem is
specific to `bsd.math`)
