Yeah tst_clone.{c,h} is the new library which uses clone3 + a
compatability layer if clone3 is not available. This avoids reinventing
a cloning API to some extent because the clone3 interface is nice IMO.

Also IMO tests should be rewritten to use tst_clone, I just haven't had
chance to do that.

BTW we need to test cloning into a CGroup, so I'll probably add that
soon.
