Hi,
I know this may have to do with my use of S3 but I'm searching for any

If I retrieve an image from boto (S3) and then try and open it with PIL I

You could look at the resize code in the C module and use the same
method to try it with the functions you use most. The trick is just
figuring out the right places to release and recapture the GIL.

When saving a CMYK file to JPG, PIL seems to invert the colors. I've
submitted a patch to Fredrik already for this, and it should be in the next
major build.
Adding a simple invert to the image before saving will help.
