For input threads that get joined during run-time instead of being
signalled to stop at termination-time as typical (e.g. an error occurs
or process exits w/ non-zero status) messages could remain in the
thread's queue and leak.
This patches threads to ensure they enter the proper "finished"
state so that the thread manager can attempt to fully process and
empty out their queues before joining them.
