--- Comment #12 from Martin Buchholz <martinrb at google dot com> ---
glibc's spawni.c does use CLONE_VM but there is other implementation magic in
that file that keeps mere mortals from using the same strategy.

./sysdeps/unix/sysv/linux/spawni.c:361:            CLONE_VM | CLONE_VFORK |
SIGCHLD, &args);
