Thanks, I hadn't heard about this option. Apparently it's designed for 
Go, whose garbage collector follows pointers to any part of the 
pointed-at object. Although this doesn't match Emacs's current GC, it 
should be an improvement. Perhaps someone could try using this option to 
build Emacs, to see whether it hurts performance or correctness.
