-------------------------------------------------------------

After some initial experimentation patching these changes into Cassandra I have 
found some strange behavior. 

It appears the message is not being broken up correctly into component parts. 
When I examine the message to retrieve the key, it appears the whole message 
body is intact within the buffer. For example when I expect to receive "k1", 
the buffer contains the entire contents of a Cassandra insert:

[0, 0, 0, 6, 105, 110, 115, 101, 114, 116, 1, 0, 0, 0, 4, 11, 0, 1, 0, 0, 0, 2, 
107, 48, 12, 0, 2, 11, 0, 3, 0, 0, 0, 8, 73, 110, 100, 101, 120, 101, 100, 49, 
0, 12, 0, 3, 11, 0, 1, 0, 0, 0, 9, 98, 105, 114, 116, 104, 100, 97, 116, 101, 
11, 0, 2, 0, 0, 0, 8, 49, 57, 55, 53, 49, 50, 51, 48, 12, 0, 3, 10, 0, 1, 0, 4, 
-116, -127, 83, 19, -95, -32, 0, 0, 8, 0, 4, 0, 0, 0, 1, 0]

Where previously, it was simply [107,49]

I will try to distill this into a reproducable test case of some sort, but 
hopefully the above can at least provide some information. 

Edit: this is with TBinaryProtocol and TFramedTransport

> Instead of using byte[] as the implementation for binary fields, let's use 
> ByteBuffer. 
> There's nothing that you can do with byte[] that you can't also do with 
> ByteBuffer, and there are more things you can do with ByteBuffer. It opens 
> the way for us to avoid needless buffer copies on serialization and 
> deserialization. It gives us a generally accepted equals() and compareTo() 
> implementation, so we don't have to have custom cases for that anymore. 
> Making this change will probably cause more than a little bit of trauma, 
> changing the method signatures in both TProtocol and generated code. It's 
> _possible_ that I could be persuaded to support a command line switch for 
> producing old-style byte[] methods in some contexts, but I'd love not to 
> waste time supporting suboptimal features.
