ui-macos/stupid.py

-import os
-
-pid = os.fork()
-if pid == 0:
-    # child
-    try:
-        os.setsid()
-        #os.execvp('sudo', ['sudo', 'SSH_ASKPASS=%s' % os.path.abspath('askpass.py'), 'ssh', 'afterlife', 'ls'])
-        os.execvp('ssh', ['ssh', 'afterlife', 'ls'])
-    finally:
-        os._exit(44)
-else:
-    # parent
-    os.wait()
