F11 yum strange behaviour

[Kevin J. Cummings]

I just finished updating my f9 machine, and thought I'd check my F11 
machine for updates.  It told me there were some, but then when I tried 
to update them, it renigged on me?

I thought that once yum found updates, it kept the updated metadata 
around and kept trying other mirrors until it found the updates.  Why 
did they disappear?  Why can't it find them now?  Is this a function of 
the stablemirror plugin which I haven't installed on this machine yet?
