A solution to manage threads and event data in Tkinter

[Gribouillis]

Making a note to read over morning coffee.

A related read is that of wxAnyThread which implements a similar idea for wxPython, where a thread can invoke a function that is executed by the main thread. This module is already 13 years old (2010), I don't know if it is of any use in modern wxPython since I haven't written a line of wxPython during all these years.

The next step for managetkeventdata is to add a proxy class that can also receive values returned from calls. I'll probably implement that using threading.Conditions objects.
