If you have a way to implement self-healing code in D please 
share it. Or forwarding pointers, or card marking, or read/write 
barriers without abusing the MMU(which is dog slow,) or...

Any of these would require massive changes to D that will never 
happen. But while everyone is tripping over themselves to try and 
copy something that will *not* work in D, they refuse to 
acknowledge what massive benefits D's GC can provide over Java's.
