<https://reviews.apache.org/r/35484/#comment141135>

    The reallocation loops will run infinitely if we have it the maximum buffer 
size. This can be reproduced by reading a JSON file with a lot of large lists. 
This could be fixed by re-intriducing the code we had before re-allocation, but 
only in the case where we hit one of these limits. Allocations should be able 
to fail, and we need to make sure the operators can handle this case.
    
    We should fail with an OOM error in these cases until we can split lists 
across batches or find another way around the fact that the allocator tracks 
buffer lengths with ints.
