I just ran through calling the above from TRAPALRM while watching zsh with
strace.  Unless there's an error (/etc/devhost not found or not readable are
pretty much the only possible ones), *nothing* touches the tty device.

If there's an error, it gets printed and then ZLE resets the tty modes
and redraws the prompt; it's the tty mode setting in that case that causes
the access time to change.

This on a RedHat Linux system; it could be different on another OS.
