 I am observing these problems:
 1. It doesn't immediately exit on Ctrl-C, but still runs for ~4-5 sec and
 then exits. But when I press Ctrl-C and ENTER - this makes it exit after
 ENTER. This is unconventional behavior, and nyx should just exit on Ctrl-C
 right away.
 2. Sometimes (in ~5% cases) pressing Ctrl-C causes the terminal state be
 modified (against what it was before). Not sure if this is ncurses bug,
 but I doubt.
 3. Once pressing Ctrl-C caused nyx to hang and it had to be killed.

 Ideal behavior: Exit back into terminal after single Ctrl-C without any
 side-effects.

 I am not sure if this is FreeBSD specific problem or not, it is unlikely.
