This removes excess mutual exclusion, and reduces the
eagerness of updating the value of a watermark.

Return null evaluators from Unavailable Reads
Null TransformEvaluators for sources represent a source where all splits
are currently in use or completed.
Update TransformExecutor to handle null evaluators properly.
Change TransformExecutor to a Runnable.

> DirectPipelineRunner: support for unbounded collections
> -------------------------------------------------------
>
> Key: BEAM-22
> URL: https://issues.apache.org/jira/browse/BEAM-22
> Project: Beam
> Issue Type: Improvement
> Components: runner-direct
> Reporter: Davor Bonaci
> Assignee: Thomas Groh
>
> DirectPipelineRunner currently runs over bounded PCollections only, and
> implements only a portion of the Beam Model.
> We should improve it to faithfully implement the full Beam Model, such as add
> ability to run over unbounded PCollections, and better resemble execution
> model in a distributed system.
> This further enables features such as a testing source which may simulate
> late data and test triggers in the pipeline. Finally, we may want to expose
> an option to select between "debug" (single threaded), "chaos monkey" (test
> as many model requirements as possible), and "performance" (multi-threaded).
> more testing (chaos monkey)
> Once this is done, we should update this StackOverflow question:
> http://stackoverflow.com/questions/35350113/testing-triggers-with-processing-time/35401426#35401426
