Just a thought ... are there any UV processes running as root?  Perhaps
uv.rc -stop doesn't stop those for some reason.

I recall a discussion recently about someone always running such a process
in case a user process running PORT.STATUS aborted, leaving the semaphore
locked, in which case only a root (uvadm?) process can unlock it.
