atexit.register in case of errors

[Andrea Crotti]

I have the following very simplified situation

from atexit import register


def goodbye():
     print("saying goodbye")


def main():
     while True:
         var = raw_input("read something")


if __name__ == '__main__':
     register(goodbye)
     main()


But in my case the "goodbye" function is deleting the logging file which 
was created
during the application execution.
Now the problem is that it *always* executes, even when the applications 
quits for
some bad errors.

Is there a way to have an exit hook, which doesn't execute in case of 
errors?
I've seen the code of atexit and it apparently doesn't know anything 
about the current
status and why the application is actually quitting, is that correct?
