I don't really know to be honest. Try the experimental approach
and keep an eye on `top`, and let us know the results. :) See the
grass wiki FAQ for a hint on adding temporary swap space on Linux
if you need it.

r.in.xyz can handle many billions of points without trouble for
non-exotic statistical aggregations; memory use there is more a
matter of raster region size and you can do multi-pass if memory
is an issue on a really really huge region.
