	Standard ISC DHCP release 3.1.2 (or earlier, AFAICS) doesn't 
	allow using OMAPI to set the 'ends' property of a lease.  
	Release 4.1.0 does.  I'm not aware (but happy to learn!) of 
	other/better ways to release a lease.

	I had occasion to look at these sources just yesterday, and
	to patch in the 4.1.0 code fragment (in server/omapi.c) to 
	3.1.0.

	Code in 4.1.0 to allow setting the 'ends' property is only
	cosmetically different from Christof Chen's patch, easily
	found using Google, and posted to this list on 25 Feb 2009
	under the subject "free a lease via omshell".

	I'm not aware of what any of the distro houses provides.
