I think we only need to care about the setxxx
calls, not any of the getxxx calls.

And we never call the setxx calls directly,
but always through the wrappers in source3/lib/util_sec.c
so if we make them call the syscalls directly we should be
ok (IMHO). Plus the wrappers always do a getXXX
check afterwards to ensure the set succeeded, and
abort the entire process if any of them failed.
