Uh, I didn't say that I am intimidated when I see Rebin. It is just
that, like James absolutely correctly noted, on modern high-clock
machines the loops often aren't slower than memory reallocations,
especially when Rebin'ing large sized arrays.
And in the case like this one, I'd believe Rebin helps if I saw some
clocking results. If the difference is more than a few milliseconds, I
admit my defeat :-)
