   Ah, now I understand the issue, thanks. Problem isn't triggered by
   number of thumbnails waiting to be decoded, but by full-sized
   images added to the queue by the viewer itself.

Yup.  It was very annoying last weekend when I was showing about 1500
photos to a (nonpaying) client to select some images.  The way I did
it should be fast (at least it was in tests) even when thumbnails are
pending, since priority requests that are already queued aren't
ignored.

   Indeed, thanks. Patch applied (the priority queue should go into 3.1.1).
   Should we have a RC3 now?

Do you have a list of remaining issues?
