Description

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)
