heh, so I picked a bad example using a socket  as that is a special  
case. Threads are also a special case for the same reason. It almost  
feels to me like a timer should be a special case too, keeping a self  
reference until it fires, or forever as long as it's mode is 2.  
Wouldn't you put a timer in the same list of special cases as a socket  
and a thread?

Thanks,
  James
