I'm hunting some strange behaviour slowdowning my set RPI2 - usb3 hub
- usb3 disk during buildworld, but I have noticed the following:

make -j6 buildworld

before r285935 -> 60145.29 real    350932.67 user     36402.54 sys
after r285935 -> 67831.38 real    196310.43 user     19135.73 sys

The kernel before r285935 was day or two older.

These are just one-run times, however the difference is quite big. The
change r285935 could influence the thing I'm investigating so it's
worse now, but still ...
