I can answer the std::part.  I attempted to introduce a fairly  
rudimentary priority system into the std::thread proposal and it ended  
up being sufficiently controversial that I pulled it in order to get  
the std::thread proposal to advance.  It is my hope (as a fallback  
position) that the "native_handle" interface will allow one to adjust  
thread priorities, albeit in a non-portable fashion.
