Not to beat a dead horse, but it might make things go faster if people 
thought of the journal as an invisible, inaccessible file, because 
everyone knows that files can be fragmented, and everyone also knows 
that fragmented files can be reassembled and serialized (cat file). 
Only possible difference is, I don't know if the reiser4 log comes out 
of debugfs in any particular order.

It's an oversimplification, but probably a useful one.
