A blocking call occurs inside a synchronization block, hence increasing monitor contention and reducing performance.
Concurrency is an important but complex aspect of modern software. As a consequence, it is often used in an incorrect way, also because the subtleties of the C# memory model are not always understood. This checker identifies a large class of common programming errors due to incorrect uses of concurrency primitives, such as incorrect implementations of the singleton pattern and incorrect uses of the volatile field modifier, whose goal is to publish a field update to all executing cores. The latter, however, has a cost in terms of execution time.
