The default space is 9 (in default-next-staff-spacing), so if you set
last-bottom-spacing stretchability to 25 (as you did originally), then it
will only want to stretch about 3 times as much as the distance between
staves. Since you have 10 staves and each one will stretch 1/3 as much as
the bottom space, the system will actually stretch about 3 times as much as
the bottom space. Since the system was bigger to begin with _and_ it
stretches much more, it will end up almost filling the page.
