You may try winpdb. I find it to be a comfortable debugger that also can attach to running programs. (You need to add a line in your code where the program should stop and wait for the debugger to attach.) I am satisfied with it, but I did not debug a multi theaded app. However, it can handle threads. I'd be glad to later hear whether it did what you need, or not:
