As a practical matter, a 16-bit short length would be better because 
buffer sizes are typically in the 1k to 64k range, and a 16-bit length 
lets the implementation pre-allocate the frame header for any message/chunk.

With an 8-bit length, the implementation either needs to shift bytes in 
the buffer when the message is 255 bytes long or it needs to preallocate 
the long frame header.
