Module Throttle.T2

module T2: sig .. end
We use a phantom type to distinguish between throttles, which have max_concurrent_jobs >= 1, and sequencers, which have max_concurrent_jobs = 1. All operations are available on both. We make the distinction because it is sometimes useful to know from the type of a throttle that it is a sequencer and that at most one job can be running at a time.
