Placing large array in object store causes segfault

[robertnishihara]

This is currently not supported due to limitations of Arrow (for compatibility with Java). It should be changed to throw an exception instead of segfaulting.

import numpy as np
import ray

x = np.random.normal(size=1000000000)
xid = ray.put(x)

The call to ray.put fails with Segmentation fault: 11.
