Coded-size in the lace for the following sizes (in octet) :

                 old     new
   0 < S <127     1       1
128 < S <254     1       2
255 < S <509     2       2
510 < S <764     3       2
765 < S <1019    4       2
etc...

So the old lacing would still be enough for all codec with frames 
usually smaller than 509. Only low bitrate codex are in this case.
And it would be more efficient for codex with some frames between 128 
and 254 octets... Anyone have some stats on real world examples ? With 
low/medium/large bitrates ? For MP3, Vorbis and AAC ?
