I wasn't able to decode /proc/[0-9]*/stat to the system CPU load, though. I think I would have to check the stime jiffy count for all processes, then see who had the largest share, but it's hard to do that real-time _and_ compare to top's output so I know I'm doing it right.
In any case, I noticed that X was using a lot of CPU system time, even though it had been reniced (manually). So I decided to start there. I restarted X, and it hasn't happened since. This is the first time I restarted X since I reconfigured it to run a 0 nice, not -10. It seems that manually renicing the running application doesn't have the same effect as editing the config and restarting. I guess there's some use for rebooting your computer ouside of a kernel upgrade or a bootloader splash screen change (even though I still haven't done that: I only restarted X ;-) Justin -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
