Tkinter messagebox and using datetime/timedelta

[Larz60+]

There are seven forms of message box. Each of these request some sort of input from the user before continuing with the current process.

I think it would be possible to create multiple messages if each were issued in a separate thread (ended when a response was received). This could, however cause some issues if allowed to run for an extended length of time without response to any of the messages. Perhaps a limit on how many are issued, which would require a notification from each thread when completed.
