- Technical flaws have been fixed, though t.regtest may suggest ideas
 - Many tests fail on account of numerical output that differs slightly
 - Several tests suffer from word clashes; more at 64 kB than at 1 MB
 - Rediculously small fixmaps like 4 kB cause word clashes to aggrevate
 - A few tests suffer from not being able to reproduce words
 - See bogofilter/doc/fixmap-errors.md for a discussion of tests
 - Wrote README.fixmap and fixmap-errors.md
