Was order of execution in Thread ever guaranteed? The output, for instance,
is different between my two machines, even on the same version of ruby:

    $ ruby -ve 'Thread.new { puts "a" }; puts "b"'
    ruby 1.9.0 (2008-02-16 revision 3) [i686-linux]
    b

    $ ruby -ve 'Thread.new { puts "a" }; puts "b"'
    ruby 1.9.0 (2008-02-16 revision 3) [i686-darwin8.9.1]
    ba

If I needed to ensure a thread finishes before exiting, I would #join it.
