I blame nasty scripts, mining my surfing habits.  The long shutdowns
are worst after I've been going through my morning eBay routines -
opening a great many eBay ads in succession.  It's not confined to
the number of tabs opened - I don't use tabs - I just open & close
windows, jumping between a search window and successive ad windows,
which I close to return to the search window.  If I then turn to real
work, such as, I find the PC quite sluggish unless I
exit FF.  When I do that, the CPU usage meter pegs for several minutes.
My solution has been to play two or three games of Freecell until
everything calms down.

I identify nasty scripts because eBay is notorious for targeted ads,
whose targets they identify with those scripts.  eBay is also notorious
for sloppy programming.

The solution may come from a method of identifying the nasty scripts or
the IP addresses to whom their outputs are addressed.  If I could do
that, I would then use my hosts file to devnull the activities of those
scripts.  It would be like skipping the commercials with MythTV.
