Allowing Ctrl-C to interrupt a python C-extension

Question

I\'m running some computationally heavy simulation in (home-made) C-based python extensions. Occasionally I get stuff wrong and would like to terminate a simulation. However

Answer 1

I would redesign the C extensions so that they don't run for a long period.

So, split them into more elementary steps (each running for a short period of time, e.g. 10 to 50 milliseconds), and have these more elementary steps called by Python code.

continuation passing style might be relevant to understand, as a programming style...
