Comment (by sean@…):

 Replying to [comment:5 mk@…]:
 > The question is whether we'd need to wait for the other OSX versions, or
 can simply conclude from Mavericks' successful build that it can be
 switched on in general?

 Be careful there. Building in parallel on your machine doesn't guarantee
 that it works on others. For example, take a look at #28878 and #23531.
 That being said, I think those issues are old and probably due to gcc-4.2.
 I would be in favor of setting parallel building for both qt5 and also for
 boost.
