Output is that of "ps -fljt ttyq4" with irrelevant (preexisting) processes
on that tty removed; zsh started as "./Src/zsh +Z -f".

This version of zsh has different behavior than the current one, it turns
out now I see it interactively: it just hangs uninterruptibly (except by
SIGKILL) after the ^Z, with no prompt and no additional printout of any
kind. My expect script was supposed to have caught that and flagged it as a
problem; I'm not sure what happened there.
