Summary: Does not play well with Tkinter when on-quit handler invoked

Initial Comment:
The following program:

import Tkinter
import sys

root = Tkinter.Tk()

console = Tkinter.Button(root, text='Done', 
command=root.quit)
console.pack()

root.mainloop()

locks up the running program if "Done" is pressed. The 
program stops locking when the Shell window is closed.

I observed this behaviour on Windows 2000, running 
ASPN Python 2.2.

The same behavior occurs when the command is "sys.exit".

Since the 'Close Window' widget works correctly, I looked at 
the Tkinter source to learn what was different. But I didn't go 
very far before I encountered some example code in 
Tkinter.py which uses tk.destroy as the command (where 
tk=Tk()).

Once I change to "destroy", the given code exits correctly, 
erasing the window.

Windows XP. IdleFork 0.92a. Python 2.2.2

Confirmed on IDLEfork/Linux.  Code can be Run again, though,
don't need to close shell.   Is that true for Windows?

Same program crashes Python IDLE on second button press,
something about a Tk callback error.  Probably some kind of
self abuse issue?
