The rational was to avoid copying of the values bytes when such value are biggish. This has
a cost however, especially with lots of small values, and as suggested in CASSANDRA-5422,
this might well be a more common scenario for Cassandra, so let's consider directly serializing
in a newly allocated buffer.
