How can you be sure that the other threads ever see it in time? they might be suspended for a whole second because a HDD needs to spin up or something like that.

So threads never seeing the value is already a valid outcome, so the compiler might as well always do that.

a real syncing mechanism would introduce compiler barriers that prevent such an optimization.
