-/**
- *  Similar to a weakptr in java, a Relay allows for a back-ptr to an
- *  object to be "safe", without using a hard reference-count.
- *
- *  Typically, the target creates a Relay with a pointer to itself. Whenever it
- *  wants to have another object maintain a safe-ptr to it, it gives them a
- *  Relay, which they ref()/unref(). Through the Relay each external object can
- *  retrieve a pointer to the Target. However, when the Target goes away, it
- *  clears the Relay pointer to it (relay->set(NULL)) and then unref()s the
- *  Relay. The other objects still have a ref on the Relay, but now when they
- *  call get() the receive a NULL.
