Hi Jong,

I'm testing again.  Looking back into the tests messages, I see that slapd 
actually core dumped, which is why the results dropped so low.  I've not 
had the stock 2.3.4 with BDB 4.2.52+patches core dump on me any time 
previously, so this would be a new behavior.

I've reloaded the database from scratch, and am re-testing.
