I also had some unclearness when I modified variables "above" the
fthread's closure (?).
Apple's "block" implementation makes outer variables read only, but fthreads are
often synchronous (that's why I use them), so modification can work.

That's right, but tornado/python only offers you one logical thread, so you're
still passing your local variables from step to step.
