Not really. You can get around it for now by setting system-count to
something in the \paper block. The reason is that, at the time we decide
on the page breaking, we haven't finalized the line breaking yet.
Therefore we don't have the real Y-extents available (except when you
set system-count because that tells us to fix the lines before doing the
page breaking).

The real solution is to make the extent estimates more accurate.
