/**
* A map from Java object addresses to native objects.
*
* Use getNative and setNative to simplify accessing this map. getNative takes
* a handle, so callers don't need to dereference its address, while setNative
* returns the native, so callers can chain it with a local variable assignment.
*
* Currently this only supports mapping an address to a single native.
* Will we ever want to map multiple natives to an address? If so, we'll need
* to do something more sophisticated here.
*
* XXX Figure out how to collect a native when its Java object is collected.
