I don't think the rewrite story is completely apocryphal. Back in way earlier development days, we had both Interlink and IBM TCP/IP stacks. I remember seeing the PASCAL load libraries in the IBM TCP procs, and I remember commenting to myself, "No wonder it's a pig." I've heard the "taken from VM's TCP/IP stack" story from several different sources, too.
(I had some run-ins with VS PASCAL back in the 1980's. I still have deep scars.)
