It's unclear what purpose thread-local storage serves in this context.
You already have a Dwarf *. I would consider adding some sort of
clone function which creates a shallow Dwarf * with its own embedded
allocator or something like that. This assumes that memory allocation
is actually a performance problem, otherwise you could let malloc
handle the details.
