Do I take this "not granted to any user" as "no +x bit is set for owner, group or other", and "a process with appropriate privileges" as "running as root"? The latter half feels iffy, if the system is still allowed to fail execution by "a process with appropriate privileges", leading to inconsistent answer from access(2) and behaviour by execv(2). But at least that explains what was observed. > I believe that's what's occurring here.
