I think the section "Multicolumn Processing" beginning on page 391 from 
the Unix Text Processing book[1] might be helpful.  It explains a simple 
macro to do two-column processing.

Although it does not solve your issue since it also implements a page 
break if you go from one column to two, I found these macro to be simple 
enough to bend to my needs.
