As it says, pushed out as testing...  Togreg is non rebasing so only
gets pushed out publicly once all the trivial stuff the autobuilders
find has been sorted.

Depending on how busy I am it can be a few days before I get a chance
to push out togreg, whereas testing goes every few patches when I'm
merging stuff.
