Reaching the culmination of having your big project merged after
a long time is always a little scary. For now, kick back and open
a Tignanello, and brace yourself for tending to potential bug
reports once the 4.12 merge window opens.

We may as well queue it up now, I don't think there's much point in
deferring an extra cycle.

Hi Jens,
apparently no complain of any sort on this last series.  Do you think
we could make it for 4.12, or shall we aim at 4.13?

Hi Jens,
apparently no complain of any sort on this last series.  Do you think
we could make it for 4.12, or shall we aim at 4.13?
