>Description:
racoon calls daemon() and then creates its control socket.
This leads to the text-book race where the racoon process has detached before it is ready.  Leading to:

# racoon -l /tmp/racoon.log
# # create a partial state on east, don't hold the hack for retransmit
# racoonctl establish-sa -w isakmp inet ${left} ${right}
send: Bad file descriptor
