ExecutionPhaseLock

case class ExecutionPhaseLock(name: String, entryBarrier: AtomicBarrier = new AtomicBarrier(), exitBarrier: AtomicBarrier = new AtomicBarrier()) extends Product with Serializable

An ExecutionPhaseLock is an abstraction to keep multiple transactions moving in a pre-selected lock-step sequence.

In order to pass a phase, we first wait on the entryBarrier. Once we are allowed to pass there, we can execute the code that belongs to this phase, and then we unblock the exitBarrier.
