# Argh! dhclient in FreeBSD 5 has a new auto-background "feature",
# it dives into the background after 10 seconds regardless of whether
# it has received a response.  This is fubar for us.  Unfortunately,
# we cannot just crank this number through the roof because it is based
# on a polling interval which actually has a rational purpose.  The timeout
# is actually (2 * polling_interval) where polling_interval is how often
# dhclient rechecks an interface without link.  We need to keep this value
# reasonable in the event that we boot up and don't immediately have link
# on the control net.  So lets try 15 seconds (30 second auto-background
# timeout) and see how things go.
