jryan,
I am at YAPC::NA 2008 and admittedly have only skim read your code. I have a couple of depth first search (DFS) iterators at:

It doesn't matter if you are letting perl manage the call stack (recursive function) or you are managing your own queue/stack (@work) - you will run into memory problems if you have to put more items on the stack then you take off. If this is the root of your problem (and I haven't read far enough to know for sure), then you will need to take a different approach.

Cheers - L~R
