Ivan - instead of using the small threshold that is killing it, if
you need just the stream network use arbitrarily large threshold and
derive your stream network from the accum file like this
r.mapcalc "mystreams=if(abs(myaccum)>30,1,null())"
or you can use abs(myaccum) instead of 1 if you need contributing
area for each stream cell.
(isn't this in the man page? I have been doing it that way for
years)

apparently it isn't. Would you mind to add it to
raster/r.terraflow/description.html
?
that is for r.watershed Helena
thanks
Markus
