A classical GC like D has is very straightforward. It is been 
used since the 60s, I even have a paper from 1974 or so 
describing the implementation used for Simula which is a precise 
stop-the world GC. Trivial to do.

Therein is the trouble, a more advanced GC is intrinsically 
linked to the language semantics and has to be tuned to the 
hardware. Expect at least 2 years of work for anything 
approaching state-of-the-art.

In the web server space you wait a lot for I/O so raw performance 
is not key for Go's success. Stability, memory usage and low 
latency is more important.
