Make sure we wipe the leases file both for server and client, so that dhclient doesn't try to re-use leases from previous tests (should really happen) and waste time waiting for a reply. Extend the timeout from 1s to 5s, sometimes it takes dhclient 1s just to start. Disable verbose mode if not needed to avoid dhclient stalling if the pipe is not being read.
