Don't know, I think a couple of hours, no more than 3 though.  I started
around 1-something, finished just before 4.  Word count is ~7600.  At my
typical 40 words output/minute for a "raw dump," that would be ~190
minutes.  Sounds like I exceeded my normal rate, possibly broke 50
words/minute.

If I made it a print article, I'd reorg, simply and slice down to around
3000-4000 words.

Everytime I threw the -O3 on a P3 doing engineering calculations
(computational fluid dynamics) back in the '90s, I got totally
difference answers.  Absolutely no precision.

Everytime I throw the -O3 on an Athlon, I get unstable software.

IMHO, it's should only be used when you wrote the software and know what
affects it will have.

It is mathematically impossible for someone who makes more than you
to be anything but richer than you.  Any tax rate that penalizes them
will also penalize you similarly (to those below you, and then below
them).  This is why someone who makes more than you always gets at
least the same, if not a bigger, tax cut.  Otherwise is impossible.
