Just for anybody searching the archives, what \markLengthOn *does* do
is space the music out to give room for the marks.  So it helps when
the RehearsalMark and tempo are on different notes, barlines, etc:

\version "2.17.19"
{ \markLengthOn
  \mark\default
  \tempo "This is a really long tempo mark"
  c''4 d'' e'' f''
  \mark\default \tempo 4=60
  g'' 1 }

A lot of people writing score-and-parts use Shevek's MarkLine context,
in which case it makes sense to include the essential bit of 
\markLengthOn in the definition of MarkLine context:
 
\score { <<
  \new MarkLine {
    \mark \default
    \tempo \markup "This is a really long tempo mark"
    s1
    \mark \default
    \tempo 4=60
    s1 }
  \new Staff {
    c''4 d'' e'' f''
    g'' 1
  } >>
\layout {
  \context {
    \name "MarkLine"
    \type "Engraver_group"
    \consists Axis_group_engraver
    \consists Output_property_engraver
    \consists Mark_engraver
    \consists Metronome_mark_engraver
    \consists Text_spanner_engraver
    \consists Time_signature_engraver
    \override TimeSignature #'stencil = #point-stencil
    \override MetronomeMark #'Y-offset = #0
    \override RehearsalMark #'Y-offset = #0
    \override RehearsalMark #'extra-spacing-width = #'(0 . 0.5)
    \override MetronomeMark #'extra-spacing-width = #'(0 . 1.5)
    \override VerticalAxisGroup #'staff-staff-spacing = #'((padding . 1))
  }
  \context {
    \Score
    \remove Metronome_mark_engraver
    \remove Mark_engraver
    \accepts MarkLine } } }
