More fine-tuning.

Please look at the diffs.

Please note, that I have not been able to find any energy consumption 
numbers to go along with the cycles for the EdDSA signing and 
verifying.  I do not believe it is trivial; not from conversations I 
have had.  Also I am not sure you can simply convert cycles to wall 
time.  This was my experience when working on ZWave. For whatever 
reason, wall time was higher than simple cycle counting predicted.

Happy reading!  Or at least diffs.  Maybe diff -21 with -24...
