It's not locking "any other device /dev/tty*". It's locking /dev/tty (it's
strcmp, not strncmp). /dev/tty is by definition current terminal. DOing a lock
on /dev/tty instead of terminal's real name would effectively lock all
processes from using their working terminals (whatever for?) and allow them to
write to the terminal that was supposed to be locked at the same time. Not
quite what it's supposed to do.
