Yes, the following message is:
cdrecord: Operation not permitted. WARNING: Cannot set RR-scheduler
cdrecord: Permission denied. WARNING: Cannot set priority using setpriority().
cdrecord: WARNING: This causes a high risk for buffer underruns.

But since 2.6 uses DMA for recording the CPU usage is really low...I guess
