Hi all,

I've got some code, which when run uses a lot of memory (aprox 600 MB for a
particular given input).  I am trying to figure out why it is using so much.

When I replace the following code:

                head.play_back do |root|
                   block.call(root)
                end

With this:

                head.play_back(&block)

And make other similar changes.  The program behaves exactly the same way,
but now uses 200MB less.  Can someone explain to me why this is the case?

I use blocks everywhere and I'm worried, they're leaking in my code.

Thanks
