Maybe. Then the result would depend on the order in which make runs the files,
but we not see any problem when running the same file repeatedly.
I could try clearing the font cache before every run of context.
How do I clear the font cache without clearing out e.g. formats?
Is it OK to just delete any fonts/ subdirectory under textmf-cache?

Yes. I should have been clearer. These 13 are not a problem.
Some files do not generate any output, as you mention.

Additional rules in my Makefile would solve this, and, I think,
a few other similar problems.

I will send you a list of files, but that list may not be very significant,
since the problem comes and goes for each source file.
