 The following code will crash when I run it on my Mac Pro (8x2.26 GHz):

 {{{
 #!/usr/local/bin/macruby

 class Foo
   def doit
   end
 end

 class Bar
   def initialize
     @foo = Foo.new
   end

   def step
     @foo.doit
   end
 end

 @bars = []
 1000.times { @bars << Bar.new }

 steps = Dispatch::Group.new
 @bars.each do |bar|
   Dispatch::Queue.concurrent.async(steps) { bar.step }
 end
 steps.wait
 }}}

 Commenting out the "@foo.doit" line prevents the crash.
