With regard the sensor sim not stopping, even though the four threads on which
join is called all join and no longer report alive, I still see four threads
sticking around after the kepler Stop button is pressed, and I never see them
reach the end of their run() methods, which I don't understand, since they're
supposably joined and dead.

I originally thought the problem was caused by use of blocking sockets,
readers, and writers. I refactored to use nio readers and writers and
socketChannels (having solved a similar blocking issue with java threads
elsewhere). However this didn't resolve the issue and four threads are still
hanging around. Stepping through with the eclipse debugger will probably be
informative...
