Also known as DoSfs for the way it fills your memory up with unwritten
crap generated by apps that didn't call fsync().

(I wonder if we can allow it to write dirty data to disk when under memory
pressure, as well? ;) )

It doesn't have to keep everything in memory. It would be a simple variation on btrfs or any similar persistent filesystem. It could write all the new data to disk but not update the root node until you bludgeon it with fsync.
