> A customer produced ORC files with very small stripe sizes (10k rows/stripe)
> by setting a small 64MB stripe size and 256K buffer size for a 54 column
> table. At that size, each of the streams only get a buffer or two before the
> stripe size is reached. The current code uses the available memory instead of
> the stripe size and thus doesn't shrink the buffer size if the JVM has much
> more memory than the stripe size.
