You understood The logic.
(I know the comment in the code are not all proper English, but I wasn't 
speaking English well at the tie :-))

If you have severals contact in the same metacontact, and you want the hostory 
for the metaconcact, we want to merge the history that are in different file 
inside one "stream"  and all the message has to be sorted.

The individual stream are already sorted, it is now just a matter of merging 
them.

Do you understand now?
