BlockingStrategy is Broken

[tvdijk]

Sequencer and SequenceBarrier each have their own wait strategy instance. This works for the other wait strategies, because they don't carry state. However, BlockingStrategy has a mutex and a condition variable, and relies on the Sequencer to signal it when an event is published, which is supposed to wake up a SequenceBarrier that is being waited on.

This signalling currently has no effect because the Sequencer is signalling a different instance of BlockingStrategy (and thus condition variable) than the SequenceBarrier is waiting on. These two classes should be sharing the same instance of BlockingStrategy. I see no way of doing that in the code currently.
