Description

Similar to the way that

Get(const std::vector<ObjectID>& object_ids, int64_t timeout_ms, std::vector<ObjectBuffer>* out)

 releases the object when the shared_ptr<PlasmaBuffer> inside of ObjectBuffer goes out of scope, the same should happen for

  Status Create(const ObjectID& object_id, int64_t data_size, const uint8_t* metadata,
                int64_t metadata_size, std::shared_ptr<Buffer>* data);

At the moment people have to remember calling Release() after they created and sealed the object and that can make the use of the C++ API cumbersome.

Thanks to anuragkh for reporting this.
