Hi Phil
Thanks for taking a look at the dbench failures.  

I confirmed yesterday that revision 1.32 of
src/kernel/linux-2.6/dcache.c is the last revision to pass dbench.
Sam already knows that's a suspect area.  I'm just saying by starting
with HEAD and reverting that one file to 1.32 dbench (and all the
other nightlies) pass. 

Why do subsequent revisions make pvfs2-client-core blow up? no idea.
It's no small change, and related if I remember correctly to Sam and
Kevin debugging some BGP issues, so reverting it doesn't seem like the
right thing to do.
