Steps to reproduce:
1) Start script session (same issue when script is saving to /dev/null)
script # or: script /dev/null
2) Tail a file
tail -f /var/log/syslog
3) Press "Enter" 2 times
4) Notice the script process taking 100% CPU
This regression is rather new but I don't know which update introduced it. Reverting util-linux/bsdutils to the previous version doesn't help so maybe it's not even script's fault. tail/coreutils hasn't been update in a long time so I'm not sure who's fault it is. I can reproduce the problem with kernel 4.4.0-9-generic and 4.4.0-10-generic.
