Create a new task object with function callback. The task function callback will be run in a loop. until the thread is interrupted by the deconstructor.

A function may return payload which is then pushed to a synchronized message queue.

A task should return in a reasonable amount of time or may block forever under the following conditions:

- The blocking call is interruptible.
- The task polls the interrupt condition.

Parameters

  task_fcn | the task callback function

Returns
  a new task object
