docs: Run `func` at a later `time` in a dedicated `channel`
  
      Given an arbitrary function, call this function after a given
      timeout. It will ensure that only one "job" is running within
      the given channel at any one time and cancel any currently
      running job if a new job is submitted before the timeout.
