Dependencies fetched in DEP GET stage

[pnorman]

While redacting changeset 8063964 the bot is fetching the dependencies of all the objects in the single-threaded stage intended for dependencies of dependencies. It should be fetching all of these objects in the multi-threaded stage. The time spent between the Threads: display and Processing indicates it's fetching but all the DEP GET lines appear to be objects that are in the changeset and it should of fetched in parallel.
