(see >rtprio(2) :-) I might try this, though it isn't really a problem I need to solve - the machine where it happens is dedicated to the job and is so slow anyhow that noone in their right mind uses it for anything complex (I compiled a kernel on it once, took about 6 hours). When left alone, it works perfectly fine. Thanks for the idea, though. Andrew.
