I've recently faced the case where the page breaker (or so it seems)
actually does not finish its job. That was with a ~100-score book, on a
machine with 3Gbytes of RAM, with LilyPond 2.11.23. After the last
"Preprocessing graphical objects...", the lilypond process uses ~1Gbyte
of memory, then slowly increases up to using all the memory available,
wthout finishing.

There have been some reports that somewhere in the recent 2.11
versions, the memory use has regressed. This is probably not related
to Page breaking.

I'll have a look over the weekend to see if I can see anything.
