@koakuma Sadly only lockfree and not waitfree.
@robryk Is there something like that that can be made waitfree?
@robryk In particular I really like how it only requires that you are able to reserve one bit per pointer for the tag (instead of making you install a permanent per-thread data of some sort)
Makes it suitable for shims in the style of libatomic lole

But it does make you install semi-permanent per-operation data (the descriptors cannot be cleaned up until way later -- if you wanted to clean them up immediately you'd be back up to 2k CASes -- and even if they could you'd need to let them stay at least dereferencable-but-with-arbitrary-content for nearly as long).
