For all interested, I have come up with a solution that may be useful to
others. In my example I had a two line exercise and four variations, also
two lines each that I wanted to format over two pages as it would not fit on
one page. The default settings produced two results somewhat consistently
and I am not sure what made the layout come out differently. The initial
exercise and three variations would be on page one and the fourth on page
two. Alternately I sometimes got the first line of variation four on the
first page with the second line on page two.
    The solution seemed to involve spacing things out so that Lilypond chose
to put the third and fourth variations on the second page. This is what my
file ended up looking like:

\version "2.4.0"
\include "english.ly"
#(set-default-paper-size "letter")

\paper {
    betweensystemspace = 3 \cm
    aftertitlespace = 5 \mm
    betweentitlespace = 1 \cm
    beforetitlespace = 2 \cm
}

\book {
\header {
    title = "Variations on an Exercise by Barreiro"
}

********************** FILE ENDS HERE *********************************

Another interesting point is that the examples in the documentation show the
\paper block appearing at the end of the file. When I tried placing it
there, none of the settings seemed to have any effect. The lesson here is
that sometimes in lilypond it makes a difference where things (ie. Settings)
get placed. Presumably the layout has already been figured out by the time
lily gets to the end of the file where the settings might be.
    Another thing that occurred to me was that I'm not sure what one would
do if you had a piece that spanned more than two pages and you needed to be
able to control the page break for the second and third (or more) pages. I
guess having \pageBreak work would be very useful and necessary.
