The journal is a fixed sized, circular log, so the buffer_head will be

buffer_head just to avoid pushing out more valuable memory contents
when we start getting put under memory pressure.

Thanks Ted. This makes sense.
I am working on a research project that may require more aggressive
reclaiming of these buffer_heads. If I were to implement something,
would this be an optimization the maintainers would be interested in?
Thanks again for the help,
Don
