Processes running even after reboot since update
 

The following process events take place while running "top" in Xterminal that did not appear to happen (at least not as prominently) prior to the update:

1. Tracker runs for about one minute at 60% to 90% of CPU.
2. Browsersd (two running at once and 17% space total)
3. Mediaplayer (5% space)
4. libeexec gst (taking up 23% of memory, but toggles on and off)
5. Imageviewer (5% space)

I have a toggling 15% to 60% of memory taken by processes even after rebooting and running no apps. Why after the update would this happen? I have no widgets on my desktop and only one brower bookmark shortcut.

Why would these be running even after a reboot? Due to Flash games hanging, I have used Xterminal a lot to review open processes and these all appear to be prominent when not noticed before.
