More testing with the old columns mechanism instead of columnset:

\startcolumns[n=2] produces roughly the same result as no columns, the
text stops short of the bottom of the page. However, the
\definelayout[current] workaround I mentioned does not solve the
problem in this case.

I'm quite willing to abandon the columnset mechanism if I can get a
working solution with columns.
