I mean, instead of trying to lower the priority of the main process, 
assign it SCHED_RR? That way it would always get executed before any 
regular process, but still it wouldn't stop the real high-prio 
SCHED_FIFO process from running most of the time. Or fiddle something 
with the realtime priorities...

Yes, that one is actually set in my config, but guess, I am running 
amd64... That explains the lot.
