CONCURRENT_PROCESS_TEST_COUNT: int = (source)

The number of concurrent processes to use to stress-test the spawnProcess API. This value is tuned to a number of processes which has been determined to stay below various experimentally-determined limitations of our supported platforms. Particularly, Windows XP seems to have some undocumented limitations which cause spurious failures if this value is pushed too high. Please see this ticket for a discussion of how we arrived at its current value.
