The problem is that TLS was already in widespread use for "thread local storage".

Transport Layer Security is widely documented as beginning in 1999.

I can find references to "Thread Local Storage" going back to at least 1996. That particular term seems more common in the Microsoft (and maybe IBM, does anyone have an OS/2 programming manual?) world at the time; Pthreads (1995) and Unix in general tended to call it "thread-specific data".

It's possible that the highly influential 2001 Itanium ABI document (which directly led to Drepper's TLS paper) brought the term to (widespread) use in the broader Unix world, though Sun (for both Solaris and Java?) was using the term previously. But it's also possible that I'm just missing the reference material.

I don’t doubt that, but I never heard Thread Local Storage until much later than that. While it might well’ve been common within its ecosystem, I don’t think it was widely known outside it.

I might have an OS/2 programming manual. But I don't need it. (-: This was not an OS/2 thing. We had to make map data structures using thread IDs. Or our language runtimes did.

Look to Windows NT rather than to OS/2 for thread-local storage. TlsAlloc() et al. were in the Win32 API right from NT 3.1, I think.

tls meaning thread local storage goes back at least to 1992 when Win32 was released. pthreads and Java are obviously much later.
