time.Sleep（）是否会阻塞上下文？

Documentation mentions that, Sleep pauses the current goroutine(G) for at least the duration d.

G cannot be in run-queue(grey circles below) for duration d.

P is context. M is kernel thread

Assume there are 8 kernel threads(because 8 core CPU - runtime.NumCPU())

Go runtime maintaining runtime.GOMAXPROCS(runtime.NumCPU()) number of contexts.

Using GO version 1.12

1) In which queue does Goroutine(G) wait for duration d? I see run-queue(above in grey)

2) In that duration d, Does that corresponding context(P) schedule another Goroutine from its run-queue on that same kernel thread(M)?

3) Can GO program schedule a Goroutine on specific context(P) run-queue?
