Fixed ABA problem in parkedWorkersStack and other stress improvements

* Workers are now numbered starting from 1, zero is used as sentinel
* Workers are lazily created (no threads initially)
* Close/shutdown of the scheduler also clears state so that subsequent
  rogue attempt to dispatch anything fails.
* Work stealing is more predictable. It starts at random index but
  then goes linearly via workers array.
