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
