"Yes, but" -- that ``if'' at the start of this quote paragraph of mine is, I believe, a meaningful qualification. It is not obvious to me that all applications and platforms can usefully execute untrusted Python code in a separate jail'd process; so, I think there would still be use cases for an in-process sandbox, although it's surely true that making one would not be trivial.
