The timing was right: the shell received SIGHUP, it interrupted read(2),
and the shell exited. This is how it happens in the vast majority of
cases.
What the original complaint refers to is what to do in the infrequent
case when the terminal goes away, the kernel doesn't deliver a SIGHUP,
and a read returns EOF instead of -1.
