Bigmachine configures a session using the bigmachine executor configured with the provided system.

Eval simultaneously evaluates a set of task graphs from the provided set of roots.

Eventer configures the session with an Eventer that will be used to log session events (for analytics).

MaxLoad configures the session with the provided max machine load.

NewTaskSubscriber returns a new TaskSubscriber.
