Hi,
I appreciate depth of information validation. Actually, you are right. vfork()
DOES work with pid=1 processes. I figured out the cause in my case. In order to
reproduce -- add unshare(CLONE_NEWTIME) just before vfork(). Now, I don't know
if it's a bug in vfork() or in fork(). Yes, both are clone() actually.

In any case, they should either both give EINVAL or both don't fail. But it's
definitely bug in the kernel around CLONE_NEWTIME.
