Sounds like the terminal is being left in non-blocking i/o mode - this
will cause reads by the shell to return EWOULDBLOCK.

You could put a wrapper round the program that resets the tty to blocking
i/o mode if it's killed; it just needs to do something like

   fcntl(open("/dev/tty"), F_SETFL, 0);
