clone3() example code

Hello Christian,

Do you have some example user-space code somewhere that illustrates
calling clone3(). I'm looking at how we might document that system
call in the manual page, and some example code to play with would be
useful at this point. (I already have a simple working test program,
but probably you have something better.)

Thanks,

Michael
