Totally, this commit spares the 10bytes copy of mcs_mask but adds a less
efficient indirection to mask.
I thought of it but kept the symmetry with mcs_mask.
Apparently you wouldn't mind the dissymmetry so I will re-send using mask
by value, plus I wrote "updates .." where it is more like "lets the
ad-hoc masks get overwritten".
