        Description

        The test creates thread pool size equals to the number of available processors.

        It is usually not a problem. But on many core machines, e.g. 48 core arm machines, running with concurrent test tasks, e.g. TEST_JOBS=4, could result undesirable circumstances, including crashing the system.

        Let's reduce the thread pool size to 1/4 of available processors.
