Good to know.  I didn't know if the behavior was defined.

You could also keep looping as long as threads exist (excluding the
primordial one of course).

Interestingly, it looks like the thread created by
TCP-SERVICE-REGISTER! isn't included in the the thread group linked to
the originating thread (I'm assuming this because it's not in the
returned list of threads from the code in my original email).  I
forget the semantics of thread groups.  Maybe I should figure out how
to get a list of all threads disregarding groups.
