He Gerhard,

Can you be more specific on what is the desired behaviour, that is 
what do you mean by "if possible they should be kept as wholes" What 
do you want in the following border cases?

1. The current page is half full, and your exercise is half-page plus 
two lines. Should TeX leave the rest of the page empty and start a new 
page, or fill the current page with exercise and put two lines in the 
next page.

2. The same case as above, but the text is one and a half page long.

3. Or a more drastic case, when the current page has only two lines 
and the text block is exactly one page long. Should the text split or 

4. Can you allow the text block to float, or should it occur where you 
place it, even if it means a lot of empty space on the page.

Basically, the difficulty is specifying how much blankspace on a page 
are you willing to accept, and under what conditions.
