I'd recommend reading Bartosz's blog on thread objects vs spawn  
(http://bartoszmilewski.wordpress.com/2009/09/01/spawning-a-thread-the-d-way/).  
It makes a really good case for why thread objects should never be  
sub-classed and therefore should be a private, hidden implementation  
detail and not a public API.
