Patch from the ISC DHCP CVS repository, fix dhclient problem, 

"Re: dhclient still taking up 95% of CPU" in current-users:

: Fix for bug #416: If a server hands dhclient an insanely large
: lease time, select() can get passed a too-large timeout, causing it
: to return EINVAL.  This fix restricts the select() timeout to one day.
