I tried using s.surf.rst in grass 5 with 10-100K bathymetry points and
eventually gave up. I couldn't get it to work in reasonable (<3days) time.
I the end I wound up using s.cellstats to calculate mean or median cell values
and use them instead. s.cellstats hasn't been ported to grass 6 so until I
get a significant bit of time to get things working I've been avoiding grass.
