Sometimes we fancy the idea of such reset function (not to restart a
thread, but to clear it completely to be reused). But I think you can
have almost the same result by writing the thread main function as a
loop, more or less like this:

co = coroutine.wrap(function (f)
       repeat
         local result = f()   -- do required computation
         -- yields last result and waits for new computation
         f = coroutine.yield(result)
       until f == nil
     end
