You may not care, but I'm sure other people would enjoy the time savings of knowing which packages can be safely built and tested with -j4, and which cannot be.  I've identified the two that don't work, and everything else seems to pass their tests when built with -j4.

(Aside from gcc & glibc, with the "known expected failures" I discussed in an earlier post.)

Everyone wants to save time--especially when it's just spent compiling things.  I spent the time figuring it out, and I think this info is useful and could be posted to the errata page. Even better would be a MAKEFLAGS-preserving trap around the 'make check' statements in the book, but errata seems sufficient.  Seems like that's the place for this kind of info (e.g., coreutils time-parsing issue breaking tests).  I'm happy to do it myself, if I'm able to...
