Since you have the situation happening, can I ask you to do two tests. Use ktrace against dhclient (without the recent execve change), and also against dhcpleased. then use kdump with the -R and -T options, and look at the timestamps to study dhcpleased's timing behaviour for querying. If there are lessons found in the timing of dhclient, maybe dhcpleased can become more forgiving.
