If choosing page size is an option, and there are only a few that are 
larger than a page, things may be much easier. Keep all of them in one 
page, and typeset. Note the ones that are larger than a page, and mark 
them using a differnt environment. That is, you decide which exercises 
should break and which should not.

This seems inconsistent with case 1. There the text was less than one 
page, but you want it to be split. In this case, the text is exactly 
one page, but you do not want it to be split?

Is something like this acceptable:

if length < 1 page
  keep the whole thing together, even if it means ending the current 
page with lots of empty space.

if length > 1 page
  split whereever you want

That would means, do a trial typesetting to find the length of the 
block, if length is less than one page put in a framedtext (which is 
just a highly customizable vbox) if length > 1 page, don't do anything 
and let it break pages anywhere. Just one more bit of information is 
needed. Do your exercises contain display math?

This is always hard to do, and TeX glue makes it harder. Things can be 
bizzare when you want to fit all you can in page limits imposed in 
conferences: removing material takes more space, adding material 
reduces space, and you end up beating your head ;)
