Similar experience. Not sure if its the same person but I had dinner with
Jeff Nick (former Felllow with Z) and his story was that they needed Posix to
meet a Federal requirement. He also said that it was contentious internally
and so they assembled a team and isolated them from the others so they could
make fast progress.
Dunno where it fits into the story, but I noticed that they used Mortice
Kern Systems "MKS Toolkit" for much of the required Unix/POSIX
utilities. (In Linux land, we'd say "the user space stuff".)
That impressed me because MKS Toolkit did the same thing for MS Windows,
a very rich approximation of Unix on top of another system. Leveraging
MKS TK was a brilliant step.
In an update on how they were doing they were finally able to fork a process.
He said it was more like foooooooooorrrrrrrrkkkkkkkk. Clearly, they fixed the
performance and little did they know that it was such a critical decision for
the platform that it saved z/OS. I think K8s is the USS of yesteryear. No
one knows it yet but it will add another 25 years to the platform.

I've worked with a few ex-OE guys, including my close colleague who used to
the IBM DE running the OE project out of POK. Let me tell you, some of the
stories they have are absolutely fascinating! It's my understanding that the
POSIX certification was mainly pursued to meet the requirements set by NASA.
But here's an interesting twist: NASA doesn't run a mainframe anymore.
