IMO, no: syslog is the one example I've thought or heard of so far
where the race involved in passing the PID does not matter.

Then you can just use LOCAL_CREDS and SCM_CREDS and you don't need any
patches at all.  (There's also effectively no race, because, as someone
pointed out upthread, UIDs don't routinely go invalid - and, often, get
reused - the way PIDs do.)
