Most of the time that's true. However, this can get very annoying if the 
phobos unit tests fail and you can't run your own tests as the runner 
aborts after the first failed test. You also can't disable the phobos 
test, as we don't have a way to disable tests.

So if you have a flaky phobos test (depends on network, datetime 
(timezone files) or something similar) pulled into your application and 
it fails, this might prevent you from testing application code. I think 
this happened to me only once, but it was really, really annoying.
