Undocumented HighGui functions

There are some functions in the HighGui module that lack any explanation/documentation. I'm speaking about startloop, stoploop (here) and startWindowThread (here)

These seem to be interesting features, as threading often leads to problems in OpenCV, and sometimes it's useful to attach a processing loop to a window.

Do you know what is the role of these functions and how do you use them?
