About kupdated and others

[Tong <mlist4suntong@yahoo.com>]

Hi, 

I notice that, many times, when my mouse become sluggish, the
kupdated is taking up much cpu resource. So,

What is this kupdated? Do I absolutely need it? How can I get rid
of it if not?

FYI, I've tried 'type' and 'slocate' searching for kupdated, but
nothing found.

Further, are the following k-demons absolutely necessary for me? I
don't run Kde at all.

$ ps -eaf | grep '\[k'
