In short, the proposed BUG_ON() prevents the memory corruption because
it is hit before something bad can happen. The result is that just the
process in question will be killed (and a tty is not released), but only
that BUG_ON() prevents that something _really_ bad happens.

I hope I could describe it now clearly. ;)
