The design of thread groups seems inadequate:
The only way to get all the threads in a thread group is with activeCount
and enumerate. But if the number of threads changes between the two method
calls, there is no way to detect this; and if there is some way to combine
the two actions into a single atomic action, it is not documented.
Better to have a design similar to Collections, where enumerate is replaced
by a (single, atomic) method that returns an array of threads.
Also, it would be convenient to have a join method for thread groups, that
joins with every thread in the group.
