Better hardware is on its way.

Presently, all documents for the development version are built, but not
published. The reason for that is that it turns out the disk space
requirements to retain all HTML and PDF files is excessive (dozens of GB
amassed during two or three weeks). I have a changeset to the build
server in my pipeline which will retain the latest set of documents.

(NB, build logs are retained and will be retained forever; they are
relatively small due to compression.)

The remaining question is how these documents will be presented in AFP.
Currently only the documents of the main sessions are linked from the
entry pages.

That is an excellent question. I still can't quite put my finger on it
as to why that single theory forces us to run AFP tests in bulky 64 bit
