pygrass.messages.Messenger.percent() smallest step is 2

[lrntct]

Even when the measured task is several hours long, Messenger.percent() displays steps two by two, instead of an expected one by one. This could give the false impression that the execution has stalled.

Bellow is a minimum working example:

from grass.pygrass.messages import Messenger
import time
total_time = 1000
msgr = Messenger()
for i in range(total_time):
    msgr.percent(i, total_time, 1)
    time.sleep(0.5)

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.
