> ConcurrentHashTable::bulk_delete might miss to delete some objects if a bucket has more than 256 entries. Current uses of ConcurrentHashTable are not harmed by this behaviour.
>
> I modified gtest:ConcurrentHashTable to detect the problem (first commit), and fixed the problem in the code (second commit).
>
> Tests passes tier1-3.
Leo Korinth has updated the pull request incrementally with two additional commits since the last revision:
- renam stack limit, and add comments
- Make ndel a reference to a pointer so that we can poison it. Also fix
POISON_PTR to be of correct type (the pointer is const, not the memory
pointed to).
