Very thorough!  Apache is a bit sloppy,  '(for-each delete-file
(find-file...) is the minimalistic scheme we adore and I'll be happy to
post a revised patch with all of that but I may wait until you've finished
the source review because there is no telling what else has Apache has
packed in there.  Please let me know.

Thanks,
Frank
