As per a thread on the mailing list [1], this issue was already fixed [2] in Neutron in Juno and backported to Icehouse, so I'm going to remove Neutron as an affected project.

This ends up causing a all hits to the nova metadata service to generate messages to retrieve data from neutron. Doing so makes a "crawl" of the metadata service take at least 8x longer than it did. cloud-init crawls the metadata service during boot. The end result is that instances boot significantly slower than they did previously. The commits are marked as having fixed bug 1276440 [1].
