Even though obstack memory management is claimed to be efficient, it is not
as efficient as it could be, because when it runs out of stack, it makes a
new allocation and copies over: For an append only structure, it would be
more efficient with a link to a new allocation.

Feel free to bring it up later, when you have less distractions. -- I think
it would be interesting to implement the open_obstack_stream function.
