Hi John,

This is not a full review, so I would recommend waiting for feedback
from others, but please:

1. Do not include the Change-Id as it is not obvious what public
   resource it references
2. As this is a fix targeted at net, please do include a Fixes tag,
   indicating the commit where this user-visible problem first
   manifested.

Also, as an aside, please wait 24h between posting updated patches.
