[pypy-dev] Getting a backtrace out of the sandbox

[Костя Лопухин]

Yes, indeed, this is the easiest way, sorry for confusion!

and remove some frames, so that information corresponds to what is
seen by the author of the script - this is slightly easier to do
inside the sandbox (no need to parse anything).
