Ah, this explains why Eli saw the problem in Emacs in a deterministic
manner, whereas I see it only with 0.3% probability in my tests on 64-bit
mingw.

In 10000 runs on 64-bit mingw, your patch went from 27 test failures
to 11 test failures. So, we're still at ca. 0.1% probability (*), far
above the 62^-6 or 10^-10 probability that one would have hoped for.

(*) I wouldn't consider these measurements reliable. Maybe the probability
did not change, and what I'm seeing is merely a measurement fluke.
