These are typical benchmark or test programs which I like to write with 
as little dependencies as possible because they compile/run on all kinds
of systems with often dubious setup.

The other issue is that everyone will have to do this now, which just
seems wrong to me. 

-Andi (who never got this strange meme which is floating around
in the kernel community for some time that cut'n'pasting interfaces
into user programs is a sane thing. To me it seems insane.)
