I swapped
BlockingCollectionforChannelso that the delivery loop can wait asynchronously for new deliveries.The current solution provided from #118 hogs threads in the thread pool by continously doing blocking operations. This causes slowdowns if you create
FakeModelinstances at scale because of how long it takes for the thread pool to grow. One of our tests went from 100ms to 30s.
