To clarify, the GC method has different behavior than how the background garbage collector works. GC calls gcStart with blocking mode, whereas the normal background garbage collector is called from proc.go <https://golang.org/src/runtime/proc.go> and malloc.go <https://golang.org/src/runtime/malloc.go> with non-blocking mode. As I read the code, GC eschews the fancy concurrent behavior of the new garbage collector.
