I would prefer to have it inside this fxn as you've shown.

You will anyway have to wait() for the thread to exit while destroying
your thread object, since if you're deleting your thread object from
outside (i.e by a user of this class), you will not have a chance to
do an "explicit" wait() since the thread object would be deleted by
then. And that could lead to the thread doing an unclean exit.
