Ok, now that we settled the details, I have some comments:
First, I think we could do with a talloc_stackframe()
instead of talloc_new(NULL). Then, I think you could speed
up the code by doing a talloc_strdup() on the header, and
then in the loop do a talloc_asprintf_append_buffer. Then
you can write the whole thing in one bunch.
