This suggests that "mdadm --incremental" is being used to assemble the arrays. Every time udev finds a new device, it gets added to whichever array is should be in. If it is called as "mdadm --incremental --run", then it will get started as soon as possible, even if it is degraded. With the "--run", it will wait until all devices are available. Even with "mdadm --incremental --run", you shouldn't get a resync if the last device is added before the array is written to. What distro are you running? What does grep -R mdadm /etc/udev show?
