Whoops - it looks like the pvfs2-client-core crash didn't really have
much to do w/ dbench. That was a red herring (a system/compile problem
on my end was what really triggered that), but I think the fixes to
address the bufmap race conditions ended up being a good thing anyway :)
Anyway, I can't vouch for the current state of dbench with pvfs2 trunk;
I think it probably still hangs the client machine just as before.

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.
