I'd got for (1) as well, it's no more then reasonable that if you want
a result you wait for it.  And I dislike libraries doing magic you
can't see, I'd prefer if I explicitly had to shut a pool down.  And
yes, if you shut the interpreter down while threads are running they
sometimes wake up at the wrong time to find the world around them
destroyed.  But that's part of programming with threads so it's not
like the futures lib suddenly makes things behave differently.

I'm glad I'm not alone in preferring (1) tough.
