its probably possible to improve its speed by interleaving the input from
several dcts. This way all elements in registers could always be handled equal
Of course that would be a bit of work to change the surrouding code to
deal with such blocks efficiently
well, you asked ;)
iam not seriously suggesting you do that work.
real review left to jason/loren/ronald/... i have too many patches and other
issues piled up ATM. in worst case just commit i trust you that your code is
not that bad to block this.

Many that live deserve death. And some that die deserve life. Can you give
it to them? Then do not be too eager to deal out death in judgement. For
even the very wise cannot see all ends. -- Gandalf
