Message:

LDAP, now with 200% more indexed queries!

Previously, only about 1/3 of our LDAP queries were actually being
answered using indices.  ns-slapd was routinely observed to be eating
a huge portion of our CPU.  Coincidence?  You be the judge.

We're going to stop being morons now and use <1% CPU for LDAP.
