The code has changed.
I just checked on a machine with 8GB of RAM and
v.distance -a -p from=ssbel from_type=centroid to=ssbel to_type=centroid
upload=dist col=dist > dist_ssbel
where ssbel has a bit more than 20000 centroids, still crashed after
memory _and_ swap go up to their max levels.
I'm aware that we're talking about 400,000,000 pairs of points, but I'm
still hoping that there is a way to avoid such heavy memory usage.
