you already have 2 solutions to this problem:

1) use CADO_DEBUG=true, which will prevent the working directory to be
   removed (of course you should also avoid using /tmp/xxx in case you
   anticipate your machine will reboot and erase everything in /tmp)

2) launch your cado-nfs.py command inside a screen or script command,
   to keep a copy of all its output
