Sorry I've been a bit AWOL here... if this diagnosis is correct, then
the problem is ultimately the memoization that needs to be thread-safe,

Is the memoization you are referring to the "set!" in the "lazy" form in
ice-9/eval.scm ? Or something else? FWIW I would not think the "set!"
could be the issue, at least on x86, but who knows.
