So?

There are plenty tracing GC algorithms to choose from:

- mark and sweep
- concurrent
- fully parallel
- pauseless
- colouring
- with nursery
- with several generations
- thread local
- real time
- soft real time
- how far interior pointers are supported
- with or without safe points
- copy on write for mutations

http://gchandbook.org/contents.html provides a good overview, 
although it has been somehow superseded by research published in 
ACM SIGPLAN and IEEE papers as well.

Plenty of opportunities for alternative implementations to plug 
into D's runtime.
