$ time ruby -e '(1..100000).collect{Thread.new{sleep 1}}.collect{|t| t.join}'

real    0m42.583s
user    0m37.693s
sys     0m1.828s

$ time ruby -e '(1..100000).collect{Thread.new{}.join}'

real    0m4.683s
user    0m3.984s
sys     0m0.245s

In the latter situation, the threads are not living side-by-side.
The second thread is started when the first one has finished.

The first example starts a lot of threads concurrently.
