I gave up on journalling myself because IMO it complicates
things a lot and the problem it solves is very very small.
The impact in disk seeks is non-trivial to predict, but it is
very hard to argue that it will not lead to an increase in
disk seeks. (This is really a variant of the age old argument
between jounaling filesystems and "traditional" filesystems)
I can only recommend that you try :-)
We need more ideas and more people trying out ideas.

Never attribute to malice what can adequately be explained by incompetence.
