Details

Jan found that pointer compression of atom and symbol pointers could save a significant amount of memory for PropertyMaps. To enable this all atoms would need to be allocated in a contiguous 4GB region.

One issue to watch out for is that child runtimes also refer to atoms allocated by the parent runtime.
