Smoothing is really slow on polarized maps

High nside maps with the fwhm parameter set take forever, and I think part of the issue is that the smoothing takes place before the sig is selected. So if I pass an I,Q,U map in with -sig 1 and -fwhm 60, first it smoothes all three channels to 1 degree and then selects Q. If this was in the other order then it would speed things up by a factor of 3, which is better than nothing
