Hmmm, if xmlNodes in doc.children have references to the parent (ie the 
xmlDoc) then this _should_ work -- the first doc won't be garbage 
collected because root.parent is referencing it. On the other hand, it 
might have created an undeletable object.

Ick! I expect the best way to resolve what happens here would be a bit of 
good old printf() debugging :)
