Page breaks are marked as undefined in CSS 2.1:

  CSS 2.1 does not define which of a set of allowed page breaks must
  be used; CSS 2.1 does not forbid a user agent from breaking at every
  possible break point, or not to break at all. But CSS 2.1 does
  recommend that user agents observe the following heuristics (while
  recognizing that they are sometimes contradictory):

  - Break as few times as possible. 
  - Make all pages that do not end with a forced break appear to have about the same height. 
  - Avoid breaking inside a replaced element.


css3-multicol says:

  The problem of breaking content into columns is similar to breaking content into pages.


If you prefer, we can make an explicit reference to CSS 2.1 section
13.3.5 from section 5 in the multicol spec?

But I don't think we can fulle describe column breaking in the
multicol spec -- we'd like for column breaking and page breaking to
remain together, and prescribing special rules for columns will not
make things easier for implementors.

Also, we don't have consensus on what to specify (as expressed by Sylvain).

BTW, the major issue preventing the multicol spec from moving along is
lack of reviewers for submitted tests. I'm going through the submitted
tests but don't feel like reviewing them as most were submitted by
Opera. Here's a log of recent changes:
