Hey Mr.Lockfree!

Have you ever implemented Hazard pointers and Michael's deque (based on
CAS64 and haz.pointers)
I'm trying to implement this algo but have poor understanding of some
tricks with memory, and how hazard pointers work

To use CAS64 on Intel, I packed 2 32bit head and tail pointers together
with queue status flag. it shares 2 lowest bits with one of the pointers.
