Summary: Migration sometimes fails: add_thread_group:Cannot move proc

Initial Comment:
For example while building the kernel under bash-ll I got:

add_thread_group:Cannot move process 416250 (cc1) - partially shared with process 2 (child_reaper)

It always seems to think processes are shared with process 2, the child reaper.

I attach a silly test script that usually causes the problem:

$ sh ./zz-migrate-cruelty
...
./zz-migrate-cruelty: line 1: echo: write error: Invalid argument
406451 migration from 6 failed want 1
$ dmesg | tail
...
add_thread_group:Cannot move process 406451 (sh) - partially shared with process 2 (child_reaper)
