This won't work in my case, because the terminal is multithreaded and=20
fork() has undetermined behaviour with threads, and because exiting the=20
parent would close file and socket descriptors, thus closing the=20
connection to the X server. A workaround would be to close the GUI=20
thread and the windows before the fork() and to open them again in the=20
child, but I'm not sure maxima users would appreciate to see their=20
window disappearing and reappearing...
