I was using np.nanmin/max because I did not yet understand how masked arrays worked; perhaps the
docs for those methods need a note indicating that "If you can take the (small?) memory hit,
use Masked Arrays instead". Now that I know different... I'm going to drop it unless you
reall want to dig into it.
