For a small number of people who have very large problems, it is
intriguing to consider that we might make dhcpd process a HUP to:

	1) Fork and execv dhcpd - continue like nothing's changed.
	2) Receive a SIGCHLD when the new dhcpd fork()s (which it
	   will do after reading dhcpd.conf and dhcpd.leases).
	3) Exit.

There is one major complication in such a mechanism.  The child
daemon MUST have a way to obtain any changes in state between the
fork and the exit.
