Cross-platform application restart?

[faulkner]

asynchronously start a process which waits for the parent to close,
then starts your script.

cmd = "python -c 'import time,os;time.sleep(2);os.system(YOUR_SCRIPT)'"
if os.name == 'nt':
    cmd = 'start ' + cmd
else:
    cmd += ' &'
subprocess.Popen(cmd, shell=True)
sys.exit()
