[Python-Dev] Event loops, PyOS_InputHook, and Tkinter

[skip@pobox.com]

    Michiel> 1) What if the user decides to import Tkinter next? Tkinter
    Michiel>    notices that PyOS_InputHook is already set, and does not
    Michiel>    reset it to its own event loop. Hence, Tkinter's events are
    Michiel>    not handled. Similarly, if a user imports Tkinter before my
    Michiel>    extension module, I don't reset PyOS_InputHook, so Tkinter's
    Michiel>    events are handled but not mine. If I were to reset
    Michiel>    PyOS_InputHook to my extension module's event loop, then my
    Michiel>    events get handled but not Tkinter's.

This sounds sort of like the situation that existed with sys.exitfunc before
the creation of the atexit module.  Can't we develop an API similar to that
so that many different event-loop-wanting packages can play nice together?
(Then again, maybe I'm just being too simpleminded.)
