G1: first GC thread coming late into the GC

        We recently tried G1 on a 32GB heap, with a 4GB / 8GB young gen. We noticed that termination times are relatively long (around 30-40ms). The reason for this is that GC worker with id 0 (it's always GC worker with id 0) is late coming into the GC code which results in all the other threads waiting for it during termination. This is clearly a performance bottleneck. We should resolve this.
