Why doesn't threading.join() return a value?

Well, still some actually.  If you use my example code (posted
elsethread), you need to know:

  - that there was a target function (my default return
    value if there is none is None); and
  - that the joined thread really did finish (if you pass
    a timeout value, rather than None, and the join times
    out, the return value is again None).

Of course, if your target function always exists and never returns
None, *then* there's no chance for confusion. :-)
