You may file an enhancement ticket - likely r.surf.contour has never

Well, it will only use 1 CPU unless being parallelized. But often a
code optimization is more efficient (as done for many modules in GRASS
GIS 7, see https://trac.osgeo.org/grass/wiki/Grass7/NewFeatures).
Maybe there is potential in r.surf.contour as well.
Just one other hint below:

... this will then become precisely 1.0.
I'll now try myself the interpolation.
