Comment:

 I change the component fom pygrass to LibGis since I see the problem also
 with C code:

 {{{
 #include<unistd.h>
 #include <grass/gis.h>


 int main()
 {
         int row;
         int nrows = 1352;

         G_message("Percent complete...");
         for (row = 0; row < nrows; row++)
         {
                 G_percent(row, nrows, 1);
                 usleep(10000);
         }
         G_percent(1, 1, 1);
         return 0;
 }

 }}}

 Looking at the `G_percent` code I don't understand when is used the
 function `G_set_percent_routine(int (*percent_routine) (int))` within the
 GRASS code and where the default percent_routine is defined.
