Description

Stress test to verify type-based contexts.

Besides a simple usage (unit) test, this test performs a massively multithreaded test of the type-based contexts, through use of the TypedCounter. The idea behind this facility is to provide a context, in which type-IDs can be allocated. In the case of the TypedCounter, these type-IDs are used to index into a vector of counters, this way allowing to access a counter for a given type.

This test builds several "families", each sharing a TypedCounter. Each of these families runs a set of member threads, which concurrently access the TypedCounter of this family. After waiting for all threads to finish, we compare the checksum built within the target objects with the checksum collected through the TypedCounters.
