It's supposed to be smart and detect which are changed and only rescan
the new ones. I wonder why this isn't working for you. Are you
operating atop a strange filesystem?

It's slow because the python imaging library is slow. I could probably
replace that backend out with something else to speed it up a bunch,
and maybe even parallelize the whole thing...
