There is an important side-effect in the way I use it in MkII: The idea is to run the table of contents independently from typesetting an entire book. For example: - you have a big book, each typesetting run takes quite long - as you also have many headings the table of contents is 17 pages - now you see an ugly page-brake at bottom of page 10 - but if the entire vertical spacing of this page would be reduced a bit then this page-break would look better. What I'd do now in MkII is such (trial-and-error loop): 0) the table of content is created by a \placelist command in a separate "contents.tex" component 1) for testing purposes I now copy the tuo file and point (via \def\FrozenTUO) the placelist run to this file 2) in this test-tuo file I hook in a command for reducing the vertical space (baseline/parskip) of my problematic contents page 3) I run the contents.tex file again to see if the result is as desired 4) if it is not, I do step 2) and 3) again 5) finally, if the result is as desired, I write the command (that gave me that desired vertical space) via \writebetweenlist directly to the original chapter's files. 6) now I point the \placelist run back again to the original tuo file: thus I can be save that whenever there will be additions/changes in the book, I can generate are table of contents with the updated pagenumbers (but also via writebetweenlist with my content's correction). That's why in MkIV I look for a way to point placelist to a specified file.
