> The framed transports in thrift wrap the underlying transport to prepend the message
size as a 4 byte value.  There are purported benefits to buffering, but the main purpose of
these wrappers is to allow non-blocking servers to perform reads without deserialization.
Of course, if the server transport is framed, the client's must be as well, and vice versa,
(framed and non-framed transports are incompatible). 
> CassandraDaemon is currently a threaded server with the default transport, I believe
we should change it to being framed, for compatibility with non-blocking clients (this actually
came up during an attempt to use a Twisted client).
> This will break all existing client apps, (even if fixing them is trivial).
