I posted this patch to fix it (read -k too)... since the symptoms it
fixes are different on my machine (it messes up the terminal but
doesn't hang) I'd appreciate a confirmation that it fixes it in this
case too.

The best theory is it's related to the fact that various terminal
stuff is now delayed in interactive shells to avoid causing problems
when the shell is put into the background.
