During process startup, system creates a process group and places the new process in it. If process group creation fails for some reason, the new child process will stay in its parent's group. This poses danger when the child is being frozen because the whole group is affected and its parent is being frozen as well. Considering that the parent of an app is Zygote, freezing it leads to the device becoming unusable. Fix this by treating group creation failure as a fatal error which would prevent the app from starting. When system_server fails to create a process group, it will throw an exception that's not caught and will self-destruct.
