Why do you think you want suspend, resume and terminate?  There are very 
few safe uses for these operations, and programs that use them tend to 
suffer from data corruption and/or deadlocks.

It would be fairly easy to add support for priority settings to 
Boost.Thread, but since priority values are only meaningful in the 
context of a scheduling policy and policies vary between operating 
systems it would be hard to provide a genuinely portable priority system.
