 The below fails wtih a segmentation fault, not sure if it is because I am
 calling in the wrong way


 {{{
 ##  Macruby test of NSOperation and NSOperationQueue

 class PageLoadOp < NSOperation
   def initialize
     return self
   end
   def main
     puts 'test'
   end
 end


 ## in awakeFromNib or whever

 queue = NSOperationQueue.alloc.init
 foobar = PageLoadOp.new

 queue.addOperation(foobar)
 sleep(10)
 }}}

 not sure if the below helps::
