Sorry, this paragraph should have referred to the "tg-id" field.  
Although the "id-in-tg" makes sense when talking about an inferior 
thread group, but not so much when talking about other kinds of thread 
groups.  If we have additional kinds of thread groups, they might not 
assign their own specific ids to threads.
