[GRASS-dev] i.pansharpen: brovey method parallelization glitch

[Markus Neteler]

Hi,

when running the manual example, I observe a strange warning:

# landsat mapset

The  method=brovey   uses parallelization for a r.mapcalc call.
Probably the calls of

            pb.wait()
            pg.wait()
            pr.wait()

are incomplete?

The maps are generated anyway.
