We've got to the stage now that saving this much memory is essential,
so this patch is a must-have.

The patch does all I would expect and no more, so approach and details
look good to me.

Performance? Discussed many years ago, but I suspect the micro-tuning
of those earlier patches wasn't as good as it is here.
