Great! I've tested that this solves the SIGKILL issue and that stty
reports the same values before and after running a UML instance.

However, the flags re not the same (before 32770 and after 34818, in
decimal). It seems that the O_NONBLOCK flag is not being restored to
its original value (off).

So now the terminal is not messed up, but the flags are still an issue
for me because having stdin/stdout in non-blocking mode breaks some of
my scripts using uml.
