This is probably because glissandi are unbreakable by default.  If you 
have one overlapping a bar line, then LilyPond cannot break there.

Consider the following:

%%%%
\version "2.19.82"
{
  \override Glissando.minimum-length = #5
  \override Glissando.springs-and-rods = #ly:spanner::set-spacing-rods
  \override Glissando.breakable = ##t
  \repeat unfold 32 { f'8\glissando e''8\glissando } f'1
}
%%%%

If you omit setting 'breakable to true, you'll see the result extends 
all on one line.
