have you checked in /proc/$(pidof stty)/fd/ to see if stty is bound to
any particular file descriptor ? Maybe you'll find the source of the
blocking operation here. You can find a unix socket attached to
another process, it may be a tty, a pipe, or even a device (eg:
/dev/random when there is no entropy left). Same for "su" BTW.
