I think that before anybody tries to seriously solve this, we need
a reproducible bug. Something that fails 5% of the time is very
difficult to solve. :(
Can you find some abusive combination of lilypond, lilypond-book,
make, -jX options to make, and CPU_COUNT=Y environment variables
to pass to said lilypond-book instances, that produces a reliable
bug? Getting that far is easily 80% of solving this problem.
