Oh! It's lovely!
Now to study effect of page- or column-break-related rules...
By happy coincidence, the document I tried it out in is one that I needed a pdf of anyway. It turns out that, without any further instructions, the text is broken into page-sized chunks, and each of those chunks is separately put into three columns of equal height. Fabulous :)
