Since I'm on the C++ binding (probably a mistake) I used:
queue.finish();
and it seems to be working.
(This also corresponds possibly to what I'm seeing on a more complex kernel;
with a more complex kernel I'm seeing on a whole pile of data on the last few Z
slices as being bogus suggesting it's not finished).
