Pivoting (or rather missing pivot)

> Different code path.

OK, I'm missing something.

Eric restored the pivot code that we don't like to step_systime()

How does the first step happen without going through there?  and/or how does 
the first step get turned into the right size double without a pivot and/or 
where does that pivot happen?

The question is how does the first big correction work?

Your analysis covers the no-big-step case.  I called that: system time is 
"close enough".
