Breaking functions run in other threads?

Will using break in a scope end any functions running in a separate thread under the same scope? If not, is there a way to do this efficiently? For instance,

i = 5

function Thingy()
    function FunctionInOtherThread()
        if i = 5 then
            for a = 1, 5 do
                print("i = 5")
                wait(10)
            end
        end
    end
    spawn(FunctionInOtherThread)
    repeat
        print("repeating til I break")
    until i == 6
    if i == 6 then break  --If I break here, will it end/stop/break FunctionInOtherThread(), in the other thread?
end

Like I wrote in the comment, would the FunctionInotherThread() break if I break Thingy()? Any help is appreciated, thanks!

P.S. I made that code up on the fly for an example, just saying. :)
