Initial tests of this patch look very promising. Now we just need to
let the DHCP servers run a couple of weeks without restart, to verify
that the memory consumption of the dhcpd process stays the same.

On the other hand, the failover peer separation problem, discussed in

https://lists.isc.org/pipermail/dhcp-users/2008-November/007426.html

is *not* solved in 4.1.1b1.
