>Description:
	If the interface, on which dhclient has negotiated a lease, is
	needed again (e.g., for renewing the lease), but has been disconneced
	then dhclient gets into a loop spewing out error messages (literally
	millions of them) about not being able to send on the interface.
>How-To-Repeat:
	start dhclient, disconnect the interface, wait.
		or
	start dhclient, disconnect the interface while it is trying
	to find a dhcp server.
>Fix:
	Give up after a certain number of I/O error.
	If the -w flag has been given dhclient should then go back to
	searching for interfaces.
