While making no claims to being in the know... ;-) My understanding 
matches yours jr.

I think the state of things is there is always more threads than +WTn 
active though often they are not consuming time. For example, there is a 
master thread sitting atop and managing the rendering threads - which 
consumes little time.

I'm not sure off the top of my head how the POV-Ray reported thread 
counts come about for photons and radiosity with respect to threads used 
and +WTn.
