Provides asynchronous resolution.

This object has a destruction-is-cancellation semantic.

Implementations should make sure that all pending requests are cancelled

when the object is destroyed and all pending callbacks will be called

shortly. If cancellation races with request completion, implementations

may choose to either cancel or satisfy the request.

may be a non-numeric named service port, and will only

be used if

does not already contain a port component.

When the lookup is complete or cancelled, the

callback

will be invoked with a status indicating the success or failure of the

lookup. Implementations should pass the appropriate statuses to the

callback. For example, callbacks might expect to receive CANCELLED or

NOT_FOUND.
