1. Most modern high-performance garbage collectors are both concurrent/incremental and generational. Generational GC is really important for throughput and I think Go will need to get it eventually.
2. The tri-color marking algorithm plus the idea of a nursery and tenured generation are all very old as far as ideas go, but the devil is in the details, and that's where the research lies. Hash tables, for example, date back to the '50s, but there's been constant research on refinements of the technique up to the present day.
