Hi,
Thanks for your reply.
The second bug is a known issue, so let’s ignore that. In that case, I
think function f still can only be executed once.
But why does the load and store of o.done need to be done using atomic
operations? I suppose there’s mutex assuring the happens-before.
I'm quite sorry for that. This is my first time posting code here.
Here's go playground link: https://play.golang.org/p/9xVjoD7rI0F.
