at first i tried just adding the setpgrp...
You mean if(setpgrp()) exit(1);?
but with that the su'd zsh doesn't ever seem to wake up. so i threw in the TIOCSPGRP calls to pass the tty pgrp to the su'd zsh... and that fixes it.
Thanks for your time and good analysis.
it looks like bash calls TIOCSPGRP directly to set the tty pgrp when it is continued... whereas zsh calls TIOCGPGRP to check it and then goes back to sleep because it doesn't own the tty.
You have done my job. ;)
ugh. this is a gross... i'm leaning towards blaming zsh for the tty pgrp problems, but blaming su for the lack of setpgrp -- su really needs to protect itself from being put to sleep by its child accidentally.
This will be done but in other way -- just by ignoring TSTP.
