[OSM-dev] mod_tile / renderd issue

I've built and installed renderd and mod_tile.

renderd receives a request.  It builds 5 images, then it deletes them!

extracted from an strace of renderd.

I can run convert_meta and it will recreate the png files, but the next
request, mod_tile doesn't use the existing .png, but requests a new one from
renderd.  renderd again creates the images and deletes them ...

This is driving me nuts.
