it doesn't list GRASS version but from the Pentium III and March 2001
references I would expect that the version of r.watershed there was
from GRASS 5.0 and using the old color setting code which proved to be
a terrible bottleneck. The r.watershed in  newer versions of GRASS can
be much much faster.
