    atomic               atomic_x86.h 
  Log:
  - membar_write on x86_64 is by default empty (since on amd64 stores are
  always ordered)
  
  - x86/x86_64 lock optimizations:  spinning on a lock should be friendlier now
    for the other cpus caches (at the extra cost of a cmp mem + jump) ; tried to
    arrange a little better the instructions to allow for some parallel
    execution.
  
  - x86 unlocks with xchg by default (since some x86s reorder stores, so a
   simple mov is unsafe)
