If group sched is available, systemd decides on its own to use it, thus making the decision to eat that overhead for me should I happen to boot say an enterprise kernel to do some performance measurements.
Perhaps there is a way to beg it to please not do that, but if so, I didn't find it in time. The service that started group scheduling was explicitly disabled by me, but systemd started it at boot despite that. Perhaps I didn't express my wishes clearly enough, or I need to burn a virgin or something to become worthy of its attention, dunno.
Applying my axe to its tentacles fixed the communication issue.
