  is alive, any other request to use `MutexLock` with this mutex will wait.

  This is particularly useful for creating a critical section when used in
  conjunction with `MutexLockIdentity`:

  ```python

  mutex = mutex_v2(
    shared_name=handle_name, container=container, name=name)

  def execute_in_critical_section(fn, *args, **kwargs):

      return nest.map_structure(tf.identity, r)
  ```

  While `fn` is running in the critical section, no other functions which wish to
  use this critical section may run.

  Often the use case is that two executions of the same graph, in parallel,
  wish to run `fn`; and we wish to ensure that only one of them executes
  at a time.  This is especially important if `fn` modifies one or more
  variables at a time.

  It is also useful if two separate functions must share a resource, but we
  wish to ensure the usage is exclusive.
