I don't really know how to use this. Is there a detailed todo list somewhere? I did find this tantalizing bit in news.txt, but when I tried to test it (by setting to option to false), I couldn't get it to work. Is there a set of tests for idle that might exercise this option?


What's New in IDLEfork 0.9b1?

*Release date: 02-Jun-2003*

- Added the delete-exitfunc option to config-main.def.  (This option is not
  included in the Options dialog.)  Setting this to True (the default) will
  cause IDLE to not run sys.exitfunc/atexit when the subprocess exits.
