I am not aware of an elegant way to handle this situation. If you find out
please let us know. It is not a Boost.Python specific problem btw. All C/C++
extensions have the same problem.

My solution is a very simple one: Almost all of our (very many) C++ functions
typically return after a few seconds at the most, most in fractions of a
second. Then Python gets a chance to handle the KeybordInterrupt. You don't
have to do anything special. I.e. simply leave that outermost loop in Python if
you can.
