dhclient sporadically eats up all processing time
my wifi interface is configured in rc.conf to run with DHCP.
After logging into the machine (Lenovo ThinkPad X61) one can see two dhclient instances running on that wifi interface, one run by _dhcp and one run by root.
The one run by user _dhcp then uses >97% processing time of one of the machine's cores.
This behaviour has been around since v3.6 (this is the version I started with dfly).
Is it normal that two chclients are running by differnet users (_dhcp, root)?
