[vtk-developers] CreateRepeatingTimer and X11/Tk

If you add "iren Start", you also have to add an "exit" following it.... (It
hangs because it leaves the Start method and there is nothing telling Tcl/Tk
to exit and clean up all the referenced objects...)
If you wait just a little bit longer,  I think I am closing in on the real
fix.

Thanks,
David
