[issue978604] wait_variable hangs at exit

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

In 3.2, winxp, (with Tkinter => tkinter), I get
invalid command name "12277720callit"
    while executing
"12277720callit"
    ("after" script)
and no new prompt and ^C ineffective. Had to kill command window.
With IDLE, get nothing and have to kill with Task Manager.
So confirmed for 3.x.
