This is interesting, can you please elaborate? 
i'm running multiple testing jobs (in devel more, i.e i compile the sources), each job creates a cobertura.ser file.
once all jobs finish, i run a merge job that merges all cobertura.ser files. 

how do i know what is the correct order or merge to use in order to get the right results? 

Eyal.
