This upgrade instruction does nothing

but can be used in an Edeliver.Relup.Modification to indicate that the processes are suspended which use changed callback modules See also Edeliver.Relup.Instructions.ResumeAppProcesses.

In a future step it might remove suspend instructions from modules which does not change exported functions and / or group the suspending of the processes in that way, that first all processes are suspended, then all code-changed and in the end resumed instead of performing this steps per module.
