the only query you can do is GC query (see `core.memory.CG` namespace, 
`addrOf()` API, for example). it will tell you if something was allocated with D 
GC or not.

yet it is not guaranteed to be fast (althru it is usually "fast enough").

i think this is all what you can get without resorting to ugly 
platform-specific hacks (that will inevitably break ;-).
