[Go] Garbage collector recycle steps in golang

Tri-Color GC Steps:
The garbage collector assigns objects to three sets:
black, grey, and white.

Concurrent GC can yield lower latencies for large heap sizes, which better then a stop-the-world collector.

• One of the costs is reduced throughput.
• Obviously, concurrency requires extra work for synchronization and duplication.
• Another cost of concurrent GC is unpredictable heap growth.
