I can't off the top of my head think of a script where I've done:

   threads = things.map { |thing| Thread.new{ process(thing) } }

where I haven't followed it with:

   threads.each { |thread| thread.join }

It's always confused me that ThreadGroup doesn't have a #join method, to 
the extent that without it I don't know what a ThreadGroup is supposed 
to be for.  I've certainly never used one.
