Had it grind on building isos in a loop for about a day and
a half, with no problems. At this point, the TODO list is
down to:

commit blockers:
	- atomics for all archs
	- docs

important, after committing:
	- repair tools

future features:
	- non-adm controlled snapshots
	- reclaiming data from deleted files is very delayed
	- performance optimization:
		- bulk block frees
		- root block faster upsert
	- small file optimizations
		- inline data

The future features can all be added without breaking disk
format -- even tweaking block sizes should be doable, as
long as blocks stay below 64k.
