  Instead of posting link can you clarify that so good with those conditional variables?
  
  As far as I understand - they simply allow to not wake up threads for check of some conditionals ?
  Is there native support for them in kernel thread scheduler or this is simply a library ?
  Is there something that they offer impossible to do in current Windows builds? Is there emulation libraries for old OS versions ?
  
  Cool functions - but not everybody will be willing to target development for nonexistent OS.
