When to use wings_io:hourglass ?

Often when I have implemented a function I want to run on a heavy mesh, I feel compelled to add a call to this function to give modest busy status info to the user.

Is this proper ?

I believe yes. Always I saw it in the code it was related to a big processing being done.

Was just wondering why I didn't seem to find it used in the core code in the ./src directory.

I have no Idea, but because someday I found it I used in my Heightmap code. I noticed we can just see the hourglass when the routine take really long time. I believe it can be useful for those you have in ML that take long time to end.
