[go-nuts] The o.done access on the once.Do function

I think you are right, all access to that field should go via atomic load/store operations. I don’t think it’s safe to mix those operations wth normal loads and stores even within the same goroutine. -- You received this message because you are subscribed to the Google Groups "golang-nuts"

[go-nuts] golang gc time STW1=>Mark=>STW2

I’m sorry I don’t understand the question you are asking but what I see from those gc times is your go busy() goroutine is blocking the STW1 phase because Go cannot currently preempt running functions. -- You received this message because you are subscribed to the Google Groups "golang-nuts"
