This doesn't seem very wise to me.... Agreed, I haven't thought of running more than one process. For the sake of reproducibility, I wouldn't want multiple processes for my test case either. I'm not sure if there are other applications than snapshot creation for such a feature, so I cannot argue whether to have each process execute such a command or not.
