OS/360 MFT & MVT back in the late 60s/early 70s had full support for threads, and distinguished between reentrant and serially-reusable modules (not to mention fully async I/O and many other things, some good). And of course, OS/360 wasn't the first commercial operating system to support such notions (Burroughs MCP on the 5500 may come close to the first, though). As for "horrid", a better description is "misunderstood" or "well disguised". The fact that all the facilities were available only to ASM programmers did much to conceal the horsepower there. There were certainly things the OS/360 didn't do very well, but they didn't lack for richness. Actually, that was the greatest weakness: OS/360 had everything in the world EXCEPT a simple way to do something. "All mechanism but no policy." Does this sound familiar? -Mike Bellcore?? Bellcore isn't allowed to hold opinions. Any here were found along the road somewhere down through the ages.
