I'd just like to note for the record that this is exactly what I had
I'd also like to note that I *agree*. Tim seems to think there's a
race condition in the threading code, but it's really much simpler
than that: the same bug can easily be provoked with a single-threaded
program: just randomly read and write alternatingly. So obviously the
people who wrote the threading code aren't interested in the bug,
because it's not in their code -- and the people who wrote the code
that doesn't behave well when abused are protected by the C standard...
