Well, I dropped this idea after realizing that it will kick us out of
primary mode in all cases. This change is an improvement (/wrt Linux
scheduling accuracy) for borderline threads, but it will cause

make both happy, at least without explicit pthread_setschedparam
invocations by the user application.
