getch() until it knows it will return something. The problem is we
can’t know that, because stdin is not affected by this KEY_RESIZE
value (it is only inserted in a ncurses internal fifo that we can’t
access).
The (ugly) solution is to handle SIGWINCH ourself, trigger the
change of the internal windows sizes stored in ncurses module, using
sizes that we get using shutil, ungetch the KEY_RESIZE value and
then call getch to handle the resize on poezio’s side properly.

The remote execution is done

very simple daemon (daemon.py) reads on that fifo, and executes any
command that is read in it. Since we can only write strings to that
fifo, each argument has to be pipes.quote()d. That way the
shlex.split on the reading-side of the daemon will be safe.
You cannot use a real command line with pipes, redirections etc, but
this function supports a simple case redirection to file: if the
before-last argument of the command is ">" or ">>", then the last
argument is considered to be a filename where the command stdout
will be written. For example you can do exec_command(["echo",
"coucou les amis coucou coucou", ">", "output.txt"]) and this will
work. If you try to do anything else, your |, [, <<, etc will be
interpreted as normal command arguments, not shell special tokens.
