I've almost inclined to that but on some thoughts on the idea,
comming to think of recovery upto target timeline, the old
segment found to be necessary for the case. Without the old
segment, we would be obliged to seek to the first segment of the
*next* timeline (Is there any (simple) means to predict where is
it?) to complete the task. Is it the right way we kick the older
one out of archive?
