Sorry for reviving this older thread, but I have the same question. Here’s another similar/same example where julia is started with `julia -t 1,1`, and the method “bar” blocks the method “foo”, which is not what I expected. This is with Julia 1.9.3.

```julia
function foo()
    x = 0
    tic = time()
    while true
        if time() - tic > 30
            break
        end
        println("inside interactive loop, x=$x")
        x += 1
        sleep(1)
    end
end

function bar()
    x = 1
    c = -1
    d = 3
    tic = time()
    while true
        if time() - tic > 30
            break
        end
        x += c/d
        c *= -1
        d += 2
    end
    @info "bar, after 30 seconds, pi is $(4*x)"
end

tsk = Threads.@spawn :interactive foo()
bar()
wait(tsk)

```

output:

```julia
[ Info: bar, after 30 seconds, pi is 3.1415926521589954
