Test:

verify TypedCounter concurrency safety

• use a set of types Dummy<i> to access a corresponding counter
• run a large number of threads in parallel, each incrementing a randomly picked counter; this is achieved by using a table of »increment operators«, where each one is tied to a specific Dummy.
