It doesn't work because the new module still uses `sched_setscheduler`, which is not implemented in musl because the Linux API is per thread, not per process as required by the POSIX API. https://github.com/void-linux/void-packages/issues/28728 I want to try if switching to `pthread_setschedparam(pthread_self(), ...)` makes it work on both libcs.
