New comment by ahesford on void-packages repository https://github.com/void-linux/void-packages/pull/39876#issuecomment-1297276791 Comment: OK, time to focus on getting this ready for Python 3.11. @tornaria if there is no more obvious fix in the next week, I'm tempted to pull your no-op delete patch in https://trac.sagemath.org/ticket/33842#comment:63. It seems the only side-effect of this patch is that stale weakrefs will persist in the dictionary. Those refs are checked when items are accessed so it should be harmless except for some wasted memory. What say you?
