Not cleaning the image cache before displaying images
Image cache cleaning was being performed during comint output filtering and, since that can happen in batches, if the total output had more images than the maximum cache size, some of them would be gone (in fact it was even worse: we were cleaning the cache after each image display). Now we just perform cache maintenance before sending the input, and avoid paying a price for non-rackets by making the cache dir setting implementation-specific.
