> This is a prerequisite for CASSANDRA-6694.
> The basic idea is to, if unsafe is available, abuse it to modify preallocated ByteBuffers
so that when they are short lived they do not need to be instantiated. Initially this will
only be helpful for comparisons and lookups on the BBs, but with some modifications to the
read path we should be able to reduce the need in CASSANDRA-6694 to construct BBs to pass
to the native protocol (thrift may have to continue as is)
