Module `Rpc_parallel__.For_testing_internal`

In order for expect tests to work properly, we need the following to happen before any tests are run, but after all the definitions of any workers used in the tests:

Master initialization In the main process, we must start the master server.

Worker initialization In spawned processes, we must start the worker server and start the Async scheduler.

We need to be especially careful in the following case: a.ml: defines worker A b.ml: defines worker B do.ml: uses worker A and worker B

Assuming a.ml and b.ml each have their own expect tests, they will need worker initialization code at their top levels. However, do.ml needs the worker initialization code to run after the definitions of the workers in a.ml and b.ml.

We use an environment variable to track the root of the dependency tree. We ensure that worker initialization only occurs at the root.
