Robert, you bring up a good point about X.  But two things:  First, my
Dell i600m has the same CPU as your machine, except that mine is a
1500MHz, a tad slower, but I have 2G of RAM and so swap is almost never
even touched.  Still, since it's my CPU which is getting jammed up by
Flash|Shockwave, perhaps measures to ease the load on the CPU generally
would be a good strategy.

Secondly, still, as said previously, when Shockwave isn't playing a
video (but with gnome and everything else running as usual), my CPU's
load avg is trivial, giving me no reason to suspect gnome or anything
else I'm running is a hog worth trimming.  All indications point to
Shockwave itself as being the problem.

NB: While writing this, yum-updated just gave me
flash-plugin-  So I've upgraded from
flash-plugin-  hopefully it's the fix I need.

Robert, thanks for the response.
