I was briefly discussing this with Andrei at (I think) DConf 
2013. I suggested moving data to a separate global GC heap on 
casting stuff to shared. Assigning types with indirections to a 
__gshared variable might also trigger this, unless we can find a 
better design. IIRC, Andrei dismissed this as impractical due to 
the overhead and need for precise scanning. I still like to think 
that it would be worth it, though, even if I can't spare the time 
for looking into an implementation right now.
