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.
