Jonas, the suggested approach that I sent earlier uses a dispatcher
to avoid this problem, which I think is the preferred approach.
Also, the poster is trying to update a GUI window *asynchronously*.
He doesn't want to use timeouts, and he doesn't want it to be button
driven. I think that justifies the use of a separate thread.

It is quite simple to open another
thread and call set_text of your label from there. The problem
is that this will probably crash your program, as gtkmm is not
thread-safe. That's why you need to make sure that your set_text
doesn't overlap with the gtk main loop that updates the GUI.
And that is the thing complicated to implement. At least
I think so. I never did this before, but you made me think about
this once again and it raised my interest, so eventually I will
come up with a solution later. Or somebody else will.
