Comment #3 on issue 1201 by percival.music.ca: GUB regtest building flakey?
http://code.google.com/p/lilypond/issues/detail?id=1201

I've reproduced it with
  make doc
without the -jX CPU_COUNT=X options.  However, I don't know where to find  
the exact command-line for the run that compiles 52/lily-23a75a14.ly.  It's  
obviously called from the huge lilypond-book command, but I don't know how  
to extract the actual lilypond call from that.  I vaguely recall that we  
*do* have some option we can set such that any lilypond-book call from our  
build system will spew out the exact command, but I don't know what it is.

Interestingly, creating a minimal .lytex file (with  
\lilypondfile{bookparts.ly} ) compiles just fine.
