Oh, good catch; I missed that.  I agree, that makes my theory dubious
at best.

Curious.  If I put together the motivation and leisure, I can
instrument that code enough (with emulator assist if necessary) to find
out what's behind this.

But I do feel fairly sure that my DEQNA emulation, which was written
from documentation and is not a logic-gate-level emulation but rather a
functional emulation, should not suffer from real-DEQNA logic bugs.
And it does trip that test often enough; here's /var/log/messagse from
the emulated VAX on my house LAN:
