I filed a bug with Oracle. Apparently, bind buffers are not peeked when you
set statistics_level = ALL in At least, not for my simple tests.

I was using statistics_level = all because it makes Cardinality Feedback so
much simpler (query 2 dictionary tables, as opposed to ripping apart 10046
and 10053 traces). So much for that idea....
