Maybe this was known, but piano staves can overflow the page with no  
overrides -- for example:

% In 2.13.24 this overflows the page by 41.4
% (two and one-half systems off the bottom of the page)
% 2.12.3 sets this on two pages
%
{ <<
\new Staff{
  \clef bass
  \repeat unfold 12 {s1 \break}
}
\new Staff {
  \clef bass
  \repeat unfold 12 {s1 \break}
} >> }
