Since LilyPond does not use floating point numbers for durations, all
this is a bit beside the point.

It is a LilyPond problem that the rational arithmetic it employs has
restrictions on the size of the fraction constituents.  If you want to
hash out some series, you run out of valid values pretty fast.  The
resulting fractions may not make a whole lot of sense but it would be a
boon if you did not have to think about approximations for such rather
special applications.  Even if it made LilyPond slow down to a crawl.
