That's true, but these tests should actually be disabled or fixed.
There's no point in having a test that everyone finds "ok" to have
it broken.

The reason to use PQM is precisely so that your commit *does* break
when you create breakage in a platform you're not running on.  Even
though you might not care about breaking someone else's environment,
I believe it's in the best interest of everyone that this doesn't
ever happen in the main line of development.

Note that I'm playing devil's advocate here.  Just like everyone else,
I do enjoy being able to commit straight to the repository and seeing
my changes there.  On the other hand, in a complex environment where
several developers and multiple platforms are involved, the only way
to bring constant stability in is to penalize those that cause breakage.
