- a toc section for every file, and records the last one seen. There are
- at least two problems with this approach:
- 1. We allocate whole bunches of toc sections that are ignored, but at
- at least we will not allocate a toc if no .toc is present.
- 2. It's not clear to me that being the last bfd read necessarily means
- that you are the last bfd closed.
- 3. Doing it on a "swap in" hook depends on when the "swap in" is called,
