I would be careful about those modes though (esp. "Old method") because they 
heuristically determine when it's time to end the paragraph (so sentences 
could actually be appended to headings).

How many gigahertz is your machine? :)
On my Pentium II, it took 8 minutes CPU time before I stopped loading it....
I'm actually going to be working on this filter in a few weeks (colour text 
via ANSI escape codes, table support...).

I don't think KWord internally uses XML (haven't checked kwdoc.cc, but).

Surely, "Sentence" mode would have have taken a similar amount of memory (it 
would be slightly less but not significantly less)?

Well there isn't really a difference in Page Formatting at all with those 
modes, just how often "paragraphs" get written.  Dunno about memory though 
but I would imagine fewer paragraphs (not "As is" mode) would be better.

IMHO, that's much too long!  But, I'm too busy to fix that at the moment.
