Is it possible to prevent errors in a looping round script with a giant pcall?

If, in some bizarre case, you have a looping round script and it breaks, your entire game is on freeze. Forever! In that case, could you possibly wrap said round script in a giant pcallas follows?

function mainRoundSequence()
    while wait() do
        -- intermission
        wait(10)
        -- load map
        wait(5)
        -- load characters
        wait(30)
        -- round over
        wait(5)
        -- articulate the round stats, start over.
    end
end

while wait(1) do
    success, err = pcall(function()
        mainRoundSequence()
    end)

    if err then print(err) end
end

Again, would this script theoretically work to make your script "break-proof"? Thanks in advance.
