------
If an actor process crashes unexpectedly, Ray will attempt to reconstruct the
actor process up to a maximum number of times. This value can be specified with
the ``max_reconstructions`` keyword, which by default is ``0``. If the maximum
number of reconstructions has been used up, then subsequent actor methods will
raise exceptions.

Ray will automatically restart actors that crash unexpectedly.
This behavior is controlled using ``max_restarts``,
which sets the maximum number of times that an actor will be restarted.
If 0, the actor won't be restarted. If -1, it will be restarted infinitely.
When an actor is restarted, its state will be recreated by rerunning its
constructor.
After the specified number of restarts, subsequent actor methods will
raise a ``RayActorError``.
