  "message": "Retain the backing device with python mapped array memory.\n\n* Fixes #3381\n* While many programs didn\u0027t suffer from this, any time references to the array memory escape to the generational collector, a subsequent collection has a high likelihood of freeing the device prior to the buffer allocated against it.\n* JAX internally seems to have a heuristic that caches a bunch of things and manually invokes the generational gc.\n* There were many other things I would like to improve about this code but I held off and just did a targeted bug fix.\n* The prior attempt (#3450) failed because with multiple results, it would have tried to get a weak reference to a tuple, which is not permitted. This more manual intervention stitches the keep-alive onto the actual objects that need it.\n",
