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. :-)
