What's the status of all that? There were interesting talks at 
DConf 2013 about precise and concurrent GCs, and it seemed that 
work was going on to fold all that into the compilers, and that 
Walter/Andrei were ready to make changes to the spec and runtime 
if needed to support precise GC. All very encouraging.

Will DMD have a precise GC by the next DConf?
