I don't know. C's type rules confuse me.  It makes sense though.
I see you're implemented a fix.  Does this always return doubles on
32-bits platforms, even when overwriting C_startup_time_seconds like
I did?  If so, we might have solved this particular "Spiffy hanging" bug.

Ah, that's a bit confusing.  The names imply that one is just more
precise than the other.

We've digressed a bit from the "Spiffy is crashing" issue, so maybe
this should.  I don't think it's a huge problem to have it here.

 and scientifically rewarding, but also because it can be an aesthetic
 experience much like composing poetry or music."
