run(code):
Run the provided Python code in the interpreter, in the current

RuntimeError in the interpreter that called ``run()``.
The current interpreter (which called ``run()``) will block until
the subinterpreter finishes running the requested code. Any
uncaught exception in that code will bubble up to the current
interpreter.
This phrase "bubble up" here is doing a lot of work :-). Can you elaborate
on what you mean? The text now makes it seem like the exception will just
pass from one interpreter into another, but that seems impossible – it'd
mean sharing not just arbitrary user defined exception classes but full
frame objects...
