I'm pretty sure Sheldon recommends a Loctite thread locker and a lockring as well in case the glue isn't strong enough, but he doesn't say if a lock-ring alone is enough.

Well, it depends on how strong and heavy a rider you are, of course, but in principle if you're going for a suicide hub, you better use loctite and
rotafixa the cog onto the hub, before threading and tightening the lockring (note: this is not the same kind of lockring used on track hubs, but I believe you know that already), that too with loctite.
Now, there will be some people who will jump up in outrage at the idea of a suicide hub, but this is what Sheldon Brown himself says about the issue:
Suicide Hub
A rather alarmist and silly name for a freewheel hub used as a fixed-gear hub.
Any standard-thread freewheel type hub will also accept a fixed-gear ("track ") sprocket . This is a common technique for converting an older bike to fixed gear on the cheap.
Despite the silly name, this is no more dangerous than using a freewheel, as long as you keep front and rear hand brakes installed.
