tweaking the linux scheduler for buildroot

Hi,

I've just read this blog entry:
http://blog.verbum.org/2011/07/18/tweaking-the-linux-scheduler-for-background-jobs/

It shows how to hint the linux scheduler about CPU intensive background jobs. I've been often hit by the fact that running a large buildroot build with a high BR2_JLEVEL in the background reduces responsiveness of your desktop considerably. Would it be considered a good idea to add an option for using "chrt --idle 0" for buildroot ?

Regards,
Sven
