Oh, that's very good news. I just upgraded from 0.90.3 a week ago,
and hadn't retested that. (As it happens I just last weekend fixed
something in my own code that had a near-identical problem with a large
signature file, and went from taking almost 2 minutes to load to less
than 1 second.)

Still, that's in a perfectly acceptable range. I should retest it so
I know how to characterize it.
