Sad Clouds in PR lib/44756. This was discussed also in: http://mail-index.netbsd.org/tech-userlevel/2011/03/17/msg004689.html

Initial work from the GSoC 2008 project by Lukasz Strzygowski. I think that this, together with the previous conversion of librt, obsoletes the tests in the semaphore/ directory. Will investigate later.
