* It's possible that there are still in-progress operations when a

* have completed before destroying it with Send__delete__().
*
* RAIIActorPtrHolder holds a singular, owning reference to a
* RemoteWorkerControllerChild actor and is responsible for destroying the
* actor in its (i.e. the holder's) destructor. This implies that all
* in-progress operations must maintain a strong reference to their
* corresponding holders and release the reference once completed/canceled.
*
* Additionally a RAIIActorPtrHolder must be initialized with a non-null actor
* and cannot be moved or copied. Therefore, the identities of two held
* actors can be compared by simply comparing their holders' addresses.
