Can you not just do a tcgetpgrp() periodically (or upon tty
setting change since modern shells change the tty settings
when entering and leaving their prompt) on the pseudo-tty
(doing it on the master side seems to work as well at least on
Linux) and use the names of the processes in that group (from
/proc for instance)?

That would have the advantage of being shell-agnostic.
