This is simply not true, because we are _not always_ going to sign
megabytes, and SDLH is more than fast enough for sensibly crafted texts.
At the end of the day we might consider the option that we don't need
a single hash function for everything.

There is a place for a high end hash function.

I insist on a second thought.

Kind regards
