Looking at the spec, we do seem to be missing SYSTEM_USER out of the
four variants the spec mentions. However, considering that we map
them all to the same thing anyway, I can't get too excited about it.
If something is done about making functions have setuid-like behavior,
we'd want to make sure that the appropriate ones of these functions
change value inside a function.
