> If the client tries to call `CreateObject` and there is not enough memory
> left in the object store to create it, an `OutOfMemory` error will be
> returned. However, the plasma store also creates an entry for the object,
> even though it failed to be created. This means that later on, if the client
> tries to create the object again, it will receive an error that the object
> already exists. Also, if the client tries to get the object, it will hang
> because the entry appears to be unsealed.
> We should fix this by only creating the object entry if the `CreateObject`
> operation succeeds.
