I think something like this would work.  (Warning un-tested code).

function resettable_thread(func)
  return coroutine.create(function()
    repeat
      coroutine.yield(pcall(func))
    until false
  end
end

It will always restart the thread with the same function.  You could use a 
more complex wrapper to allow changing the function that the thread runs.
