An array of auto_ptrs isn't as flexible as a thread_group. It's fixed size
and can't have threads dynamically added on the fly.

Implementing a thread-safe thread_group is a completely different can of
worms.

So why didn't you use "explicit management" in creating the thread_group,
but opted for "manual management" instead?
