            _StreamSlice

Truncated stream.

Takes a stream and presents a stream that is a slice of the original stream. This is used when uploading media in chunks. In later versions of Python a stream can be passed to httplib in place of the string of data to send. The problem is that httplib just blindly reads to the end of the stream. This wrapper presents a virtual stream that only reads to the end of the chunk.
