Anthony,
We were just about to start looking into the fork method for ldirectord (we
currently use an older version....)
Loadbalancer.org Ltd would be happy to sponsor a Perl hacker to increase the
performance of the ldirectord health checks,
as we don't have the right skills in house at the moment.
If anyone is interested by all means contact me off list, everything would
be contributed back to Horms/Ldirectord of course....
