> It would be useful to allow a Plasma client to abort an object that it 
> created but hasn't yet sealed. After the abort, it should appear as if the 
> object was never created all. The logic is similar to the delete case, except 
> that the client must release the object atomically with the removal of the 
> object from the cache and store.
> In Ray, for example, we need this for the distributed version of the Plasma 
> store, where many Plasma clients transfer objects to each other. If a sending 
> Plasma client fails during a transfer, we want to make sure that the 
> receiving client can abort the transfer, so that we can later recreate the 
> object successfully. Otherwise, we will fail with an error that the object 
> already exists.
