Review comment:
This testcase requires both two tasks should be assigned to the same
preferred location so `Int.MaxValue` means the rest of task which is not
assigned the preferred location first waits for the preferred location
available.
If it's concerned to hung the test, we can choose a small value but long
enough to assign to the preferred location.
