I'm not sure whether this is
- a glibc bug in the implementation of clone()
- a kernel bug in the implementation of the clone syscall
- or simply an unsupported combination of FLAGS.
The fact that the various versions of clone.S explicitly test for
CLONE_VM and CLONE_THREAD and take different action suggest that
what I'm doing in the test case should work.
I am suspecting a bug in
sysdeps/unix/sysv/linux/i386/clone.S
but this is deep magic x86 assembly language,
and I'm not competent to debug it.
