When I remove this bit, the adjtimex() issue progresses to
the shmget() issue (which seems impervious to setuidness).
When I add it back, the adjtimex() issue returns.
There is a red herring in my strace output - my output of
"errno" in shm_initialise.c was faulty.
Having fixed that, I can now see that the *actual* error
from shmget() (as implied by the SYS_307 line, I guess) is
errno 22 EINVAL (Invalid argument), and *not* 2 (No file or
directory).
