Your guess is correct about consolidation.  But there is no bug
AFAICT.

The "normal" (non-waiting case) uses "CLONE_VFORK | SIGCHLD".  The
"waiting" case uses "CLONE_KERNEL", but then that thread does another
fork with just "SIGCHLD".

ie. the actual thread which does the exec never uses CLONE_FILES.

Hope that clarifies,
Rusty.
