--------------------------------+-------------------------------------------
Reporter: robertwb | Owner: somebody
Type: defect | Status: needs_work
Priority: major | Milestone: sage-4.8
Component: coercion | Keywords: weak cache coercion
Work_issues: Get some timings | Upstream: N/A
Reviewer: | Author: Simon King
Merged: | Dependencies: #9138, #11900
--------------------------------+-------------------------------------------
Comment(by vbraun):
This is a bit hackish, but we could also store a strong reference as
before but manually `Py_DECREF` it by one. The eraser then has to make
sure that cache entries are removed when they fall out of use, or we'll
segfault....
