Hi Clark,

The operating system provides facilities for setting and changing the 
priorities of threads.  (Well, at least POSIX does; I presume that 
Windows does too.)  As I understand it, Boost.Threads doesn't provide a 
mechanism to control these priorities.  The thread class in C++0x will 
provide a "native handle" that you could use; perhaps it should provide 
a direct way to control the priorities, if there is sufficient 
commonality between the platforms?

Anyway, I'm curious to know whether the functionality that your 
priority queue implements could have been achieved using O.S. 
facilities, if they had been accessible to you.

Phil.
