I'm no expert but I thought the traditional case was fast recovery to
a consistent filesystem state (avoiding a long fsck), not recovery of
buffered data or fast writing of buffered data to disk.  I'm pretty
sure ext3, for example, with its default async mount, is very
susceptible to losing data.  ufs+softupdates most certainly can lose a
lot of buffered data.
