I don't think this one is lacking interest, but an obvious fix. It looks like Russ Cox did commit a fix for some portion of the cases. But a better fix would either need to significantly modify the way things are laid out to reduce the odds of false positives, or else move to a precise GC.
I haven't mentioned downvotes to date, but the down votes on this is puzzling. Would the down voters care to comment as to why the comment is deemed down vote worthy? (I would think those who work/grok on memory managers do get the point.)
