To be clear, it'll be a parallel GC, not a concurrent one.  The former
still stops all threads, but runs the collector on multiple cores at
once.  The latter performs collection while mutator threads are still
running, and is a lot trickier to implement.

(For a fine knee-slapping time, try reading a Java GC tuning guide.)
