You could try the old UNIX "nohup ...&" technique for running a

$ nohup python -c "import sys,os; print

appending output to nohup.out
$ cat nohup.out
False
But that is over kill I guess.
One worrying detail.... the definition of a running process in
UNIX implies is that it has standard input/output files open.
You'd be wise to make sure that they are connected to things
that are safe.... /dev/null.
Even so /dev/tty can be opened any way...
Not if you really detach from your tty: after you've detached,
there is no tty for /dev/tty to connect to and any attempt to
open it will raise IOError.
