I don't have a good picture, and didn't do the meticulous
review of the existing code, but I will take a stab anyway.
Until there is a possible breakpoint, \pagetotal may not
include the most recent contributions. You have to give
a breakpoint, even \penalty9999, to get an accurate
Since you are worried about being after section titles,
I recommend a heuristic:
Record \pagetotal (call it \subtotal)
check \if at nobreak to see if breaks are forbidden
For no-break case, choose to introduce a \penalty9999
only if \subtotal is well short of a page, say .75\pagegoal
For the else case, always give \penalty9999
Finally, check the real pagetotal.
