I just wanted to step in on this topic to point out one thing: no matter how tight the lock, there is one action the opponent will always be able to take. Unless you constantly keep a "can't attack modifier" on their hero, he can always attack your hero with his. Even if he has no weapons in play or no way of increasing his hero's ATK, it's a legal play. And as long as you don't have a ready Protector out so he won't accrue extra damage, it's actually a smart play to eat up more time.
It all boils down to this: there is never a time in a Game, for any reason, where a player is obligated or forced to concede. It is perfectly within their right to continue gameplay and force their opponent to play it out and win either through fatal damage or forcing their opponent to deck out. Consider a scenario where the person with the VFW lock may just have fewer cards in his deck than the number of damage he needs to deal, putting him in a situation where he could deck out before winning the game. This could mean a win for his opponent if they play it out rather than just conceding.
The point is, it is not unsportsmanlike or ill-mannered in any way to force the game to be played out. In some situations it's just plain playing smart, especially in situations like this where time is an issue. Maybe in a different situation it's not two or three minutes left in the round, but only one.
So when you get down to it, the player should still be playing at a relatively fast pace (even faster if they have almost no moves to make) and if they are taking too long a Judge should be called to investigate Slow Play or possibly Stalling (remember that there is a difference between the two infractions). But that doesn't mean that they can't run time down by forcing the game to play out and under no condition where they MUST concede.
