A minor thing that bothers me about this series is that it looks like
it is based on magic numbers and some redefined constant values
according to some mysterious sources ;-) .. It would be nice to have
some wording in the commit messages explaining reasoning and maybe
"semi-official" sources behind the changes.

LGMT code style wise :)
