You can't expect that. Lame's limit are specific for the algorithm
it uses. That would be the case for any lossy encoding system.

That is absolutely right. Systems such as EBU-R128 exist because
it makes perfect sense to make things sound even (avoiding your
listeners having to adjust the volume all the time), while 'maxing
out' serves no useful purpose at all - it just destroys the sound
if taken too far. In other words, such systems exist to *stop* you
'maxing out' everything.

Lame's 'replaygain' meausurement has the same purpose. Note the
value for the file in your original post: -9.1 dB. That means
that an intelligent mp3 player will *reduce* the level of this
file by 9.1 dB when playing it - it is already much too loud.
