Colin Percival 54ca359425 Two fixes here: ... 1. If fgets fails, don't go into an infinite cpu-intensive loop. Instead, check to see if the terminal still exists, and sleep(1) otherwise. 2. When we check to see if the terminal still exists, make sure we're not mislead by EINTR. This could have been a security issue, but fortunately the current implementation of tcgetattr doesn't EINTR.
