Oh, thanks for reminding me about this thread :)
I have been working on CDGC porting for some time. Currently I
have a basic version that can be built within D2 druntime and is
capable of allocating and cleaning the garbage. It still needs
some cleanup and tests do not pass because of different runtime
requirements compared to D1 but I expect to present something for
public experiments this autumn.
(thanks Sean Kelly for earlier similar effort and Martin Nowak
for explaining how to do forks properly :P)
