I’m running into an issue that I can’t wrap my head around. Here’s a MWE reduced from a more complex code:

```julia
i = 0
for j = 1:2
	global i
	i = j
	@show :before, myid(), i
	@everywhere i = remotecall_fetch(()->i, 1)
	@show :after, myid(), i
end
@show i

```

Case 1: start julia with `julia -p N` where `N` is at least 1, the output is

```julia
(:before, myid(), i) = (:before, 1, 1)
(:after, myid(), i) = (:after, 1, 1)
(:before, myid(), i) = (:before, 1, 2)
(:after, myid(), i) = (:after, 1, 1)
i = 1
1

```

Case 2: start julia with `julia` (i.e., without `-p N`), the output is

```julia
(:before, myid(), i) = (:before, 1, 1)
(:after, myid(), i) = (:after, 1, 1)
(:before, myid(), i) = (:before, 1, 2)
(:after, myid(), i) = (:after, 1, 2)
i = 2
2

```

The case 2 output is what I would expect to happen regardless of the number of processors. I don’t understand those last two outputs where `i=1` from case 1. Can anyone help me understand what is going on there? What am I missing? Is this a bug? Is this a feature?
