Simplify the Job Queue:

Browse Source 
This is a refactor aimed at cleaning up and simplifying the existing
job queue.

As of now, all jobs are cancelled at the same time and in the same
way, so this commit removes the per-job cancellation token. If the
need for such support is demonstrated, support can be re-added.

* Revise documentation for ClosureCounter and Workers.
* Simplify code, removing unnecessary function arguments and
  deduplicating expressions
* Restructure job handlers to no longer need to pass a job's
  handle to the job.
