I thought more the lines of XDM, when the X server it spawns gets killed, its restarting it, showing the login greeter again. I looked at Login.app from mGSTEP as an example: http://www.illumenos.com/os/mgstep/projects.html I could write an init script , that runs the while (1) loop, and restarts every time. Otherwise, I could potentially just write a wrapper binary, which execve() the application in a while loop.
