That worked better for me. "route -n flush" was instantaneous.

To recap, I am trying this:

kill -TERM `cat /var/run/dhclient.pid`
ifconfig em0 0.0.0.0
ifconfig em0 down
route -n flush
ifconfig em0 up
dhclient em0

This is where I have trouble still.  /var/log/messages is showing 
three items related to em0:

dhclient: send_packet: Network is down

The above repeats several times, then:

em0: The EEPROM Checksum Is Not Valid
em0: Unable to initialize the hardware
dhclient: New IP Address (em0): 10.0.0.25
dhclient: New Subnet Mask (em0): 255.255.255.0
dhclient: New Broadcast Address (em0): 10.0.0.255
dhclient: New Routers: 10.0.0.1

Yet, ifconfig em0 shows no IP address and no mask....  Attempts to 
manually set the em0 IP address result in the checksum error messages 
shown above.

I am confused by this.

I know that the the solution, at boot time, to this issue is to add 
the following to /boot/loader.conf:

hw.pci.allow_unsupported_io_range="1"

But I have no idea how to solve this at resume time.
