Wierd performance issue with 8.1cvs

Folks,

At OSDL we're seeing a wierd performance crash on 8.1cvs.   What's wierd about 
it is that it doesn't happen all the time -- about 1 out of 4 test runs.    
What it looks like happens sometimes is that performance drops dramatically 
at the first checkpoint, and never comes back.  But there's oprofiles and 
things to make a more insightful analysis:

3 test runs exhibit it:

Note that these are all different day's builds.
