- freeing buffer caches on image close does not work well, since we free regions
after images (strangely)
can we free images earlier?
vips_region_dispose() unrefs the buffer before it unrefs the image .. odd!
- below does not work for sharp .... we must free all buffers on close
- we free buffers on vips__buffer_shutdown(), called from thread shutdown,
