Use do...while in place of for(;;) for handling CAS in LFStack
Use do...while as CAS loop for BFBitset too
We don't support extra bit set methods because we can't make them thread-safe (yet)
Stack node pointers must be made volatile since
Use less test items, there's really no point in testing with so many items
Pad the node class so that each node fills a cache line (avoid false sharing)
Reduce BFBitSet memory requirements
Test the LFBitSet in a heavy contention scenario
Include ga-beacon in the README for analytics
