keep-together.within-column and margin-bottom are not friends

[Phillip Rhodes]

Using version 0.95

If I add keep-together.within-column="always" or keep-together.within- 
page="always", the bottom margins of my pages are not *always*  
respected.  As an example, on page 8 of the pdf document below.  I  
would appreciate any thoughts on how to get around this issue.

Thanks.
