Does your file contain namespaces? Klacks has a well-known memory leak where namespaces are concerned. It maintains a stack of namespaces, but never actually pops that stack.

If that's your problem, it's a trivial fix:

I am not using namespaces, however applying the fix anyway seems to keep the unbounded memory use in check. It seems that this is indeed an issue cause by the very tight loop overwhelming the gc. As soon as I do some work in the loop the memory use is bounded.
