It looks like Tilemaker converts shapefile objects into its own representation, after which point I think we can safely free the shape objects. I don't think SHPClose is sufficient to free the individual objects.
For the shapefiles used by the Shortbread tile set (1.4GB of coastline .shp files), this seems to decrease peak memory usage by ~1.7G
