In both it just shows up as a single process. When I do a ps -ef it 
appears that the ppid = 1 (root). I do also find it interesting that all 
of a sudden (today) it is using so much time. Previously my cpu usage 
was at a minimal, even with more going on. The only difference seems to 
be a kernel update that happened this morning along with some other 
software. I guess I could try booting into the earlier kernel to see if 
that's it. I don't recall what else got updated. I have also noticed 
that the GUI reports approximately half the usage that top reports per 
process.
