Is there a sleep/delay function

[phimo]

Hey folks

I did not find a solution to let my script wait for a specified time period.
The only way I achieved it is pretty bad, because its busy wait.

function Functions:Sleep(d)
    local start = Turbine.Engine.GetGameTime();
    while Turbine.Engine.GetGameTime() < start + (d/1000) do
        --nothing
    end
end

This is not really nice

Hopefully some more advanced lua scripters out there may have a solution
