Status of getting CDGC into druntime

[Joakim via Digitalmars-d]

I just stumbled across this year-old blog post on the Sociomantic 
blog, mentioning plans to get CDGC into druntime:

A google search turned up this forum thread also:

http://forum.dlang.org/thread/20130529162043.GA5161@sociomantic.com

and I notice that Luca made some commits back then:

Obviously, the work has since been sidelined, but can we get an 
update on whether you still plan to merge it and when?  Thanks.
