There is one other bit that needs to be documented in clone, although
I am not certain where/how.
The sequences:
unshare(CLONE_NEWPID).
clone(CLONE_VM)
setns(fd, CLONE_NEWPID).
clone(CLONE_VM).
Now fail.
Basically the rule is all threads must be in the same pid namespace.
The joy of reviews with good comments that come much later than hoped.
Eric
