Run with 5 MB of RAM and you'll wonder why the old limit kept over 512kb
free at all times.

In fact, I couldn't even boot 2.1.109 with mem=2M init=/bin/sh because the
system refused to use the last 400kb or so of free memory to load bash. It
was more content to just sort of give up and die than use the memory.
Assuming it booted, the first thing I would have done would be to lower the
freepages limit with /proc...
