The attached patches make our LDAP server multi-process.

This brings performance gains and losses.  Essentially if we have one
client binding and going away, strictly one at a time, then there is a
significant overhead.  However, with multiple clients we get to use
multiple CPUs and it is worth it if there are multiple incoming
connections or the connections are long-lasting. 

We hope to fix up and restore the prefork process model in the future,
but this isn't on the cards right now, and our users need the extra

Please review/push the attached patch and the performance tests.
