Benchmark use case: - obtain, and execute, a collection of event handlers (registered whiteboard style)
- try not to be slower than EventProcessorUtil ("eventProcessorUtil_process" case, invokes the current impl) To avoid the loop testing problems use a fixed size of 4 handlers in all tests. We're not trying to measure the loop speed itself, but…
