> Currently ByteBufferUtil.clone uses .mark and .reset on the passed ByteBuffer.
> This is fine when using thrift because no two ByteBuffer are being accessed at the same time, but this could be thread-unsafe if the same BB was passed concurrently.
> Solandra is having problems with this (Solandra shares JVM with Cassandra).
