The reason for the second process is to allow the dhcp-script to  be run
as root. The security exposure surface  of the main process is
sufficiently large that running it as root is not a good idea.

Note that the two processes will share much of the their memory, as they
are running the same program text, and a lot of the memory inherited by
the helper process from the main process is never touched.
