++
++        It may be in raw mode for one of two reasons:
++
++            1. All the headers of a request have been received and this
++               L{HTTPChannel} is currently receiving its body.

++               buffering the data of all subsequent requests to be parsed
++               later.
++
++        In the second state, the data will be played back later.

++        @note: This isn't really a public API, and should be invoked only by
