Nice work - that's a great test case.

So if I I run this code:

10000000.times do
   node = XML::Node.new 'node'
   #node.to_s
end

I see no issues.

Adding the .to_s does seem to cause a problem.  Are you actually doing 
so many to_s calls in your code?

Anyway, will have to look and see if there is anything obvious in the 
part of the bindings.
