The file testthread2.d is by far the slowest test in the test suite; it takes 10% of the total running time, yet it is only testing a single bug (bug 3930). It's so slow because it wasn't a fully reduced test. Now that the root cause is known, it should be possible to make a much better test. The other notably slow test is testgc3, which is a pretty useless test, because it can't even fail! It's another 4-5% of the running time.

I ran the tests just now. testthread2 -> 6s testgc3 -> 2s On my machines, it takes approximately 10 minutes to run all the runnable tests (with -j8) so I think that we can close this now.
