The odd thing, is that the "rest" of inn was compiled with largefiles. Inn
wouldn't even start without it. Especially since the buffers themselves
are all _well_ beyond the 2GB limit. And inn would refuse to start without
LFS enabled.

Things have been running smoothly so far. After rebuilding the overview and
history file, expire has been keeping the history under 2GB.
