The null implementation just provides no-op methods instead of actual locking
operations. This functions as an easy way to verify that a test case has
successfully reproduced a problem that is hidden by the other implementations.
Notice this implementation should consistently fail tests enforcing atomicity,
such as TestAtomicRename and TestCreateNonRecursive. Additional tests may
eventually fail due to unpredictable race conditions, since no lock behaviour
is being implemented.
