[boost] portable lock free algorithms

Hi there, I've just read the paper "High Performance Dynamic Lock-Free Hash Tables and List-Based Sets" by Maged M. Michael at http://www.cs.tau.ac.il/~shanir/reading%20group/p73-michael.pdf and wonder if the subject has become feasible. The paper basically states that the algorithms can be implemented on most current processor architectures using CAS or LL/CS instructions, rather than rare DCAS/CAS2 instructions. Is that true? Is there something going on in boost with regards to the subject? -- Maxim Yegorushkin
