Can you point me to a specific example?

I am currently trying this with the iterators used to evaluate XPath
sequences. I am retaining copies on a once DS_ARRAYED_STACK. So far,
this is actually increasing the runtime (but it appears sensitive to
the size of the stack, so I am currently trying with just a DS_CELL to
see if this is better).
