-  my_yield_processor (equivalent of x86 PAUSE instruction) should be used

-  Running benchmarks for spinlocks implemented with InterlockedCompareExchange
-  and YieldProcessor shows that much better performance is achieved by calling
-  YieldProcessor in a loop - that is, yielding longer. On Intel boxes setting
-  loop count in the range 200-300 brought best results.
