Is there anything in cgroups that would allow me to pass a signal from one of these tasks to all the others. It seems I can't use kill(3) because it appears all these processes would have to be in the same process group and only a single controlling terminal is allowed per process group?? Is this a correct assumption? Is there a way to eliminate the "single controlling terminal" requirement per process group? Can cgroups help me in any way? I can't use any sort of poll/select method. I need signals. Thanks and regards Mark
