For systems programming (container-like) I would like to access for example through
syscall.SysProcAttr clone flags that control the properties of forked child processes
(e.g. CLONE_NEWPID, CLONE_NEWNS, CLONE_NEWNET, CLONE_NEWUTS).

I have prepared 2 draft CLs:
- add CLONE_* constants to syscall: https://golang.org/cl/13160043/
- use clone() instead of fork() in syscall/exec_linux.c:
https://golang.org/cl/13159044/

Mount namespaces are awesome. Being able to call Unshare early in a Go program would be
nice.
