Of course, when I go back to the machine to do the "yum clean metadata", 
I notice that after 2+ hours of being online, it "suddenly" has a notice 
that there are 521 updates that I need. Fired off "yum update" and it is 
taking its sweet time doing lots and lots of updates ... as I would have 
expected after not doing such since 14feb10.

Patience clearly was not exercised on my part ...

But it is good to know about "yum clean metadata" for the future ... and 
I am still curious about your warning on "watch out for more plugins"

Thanks for bearing with,
Paul
