Two Questions ( atapicam related and scheduler related)

[Thomas Moyer]

I been following the progress of the 5.3 release and I thought they were 
changing the shceduler from SCHED_4BSD to SCHED_ULE?  Also I recently 
acquired a DVD+-RW and was wondering if I should stick with using burncd 
and growisfs with the standard /dev/acd0 or should I switch to using 
atapicam?  Is there any sort of a performance gain?  What are the 
advantages and disadvantages of both?
