Well I just read it again, and it appears to me that the shadow stack is 
something they already have implemented and it can be used for "gc 
prototyping" but if you want you can write your own code generator 
plugin and generate your own stack maps. It actually sounds more 
feasable to implement a generational GC with LLVM then with what we have 
in dmd.
