Even with 3-4, if DPS are all over the place it's going to cause ulcers.
If your DPS isn't completely retarded and knows how to focus DPS, tanking four mobs at any given time should be a non-issue. My dedicated Warrior tank doesn't even have to spam TC to keep me from pulling aggro (though me being a Resto Shaman has something to do with that), just one every so often will do it, and if the DPS isn't glued to whatever mob in the kill order he's Devestating/Shield Slamming the crap out of, they usually don't last very long in our parties.
Make sure your DPS understands that it's not the Warrior's job to keep his threat higher than theirs. It's their job to keep their threat under the threshhold the Warrior has set. The Warrior's one and only obligation is to keep mobs off the healer, who in turn will keep him and the DPS alive while they kill things. Of course, a good Warrior will do both, but the point is that managing aggro is not the sole responsibility of the Warrior; it's a group effort.
Beyond that, a Warrior's tanking limit is pretty much four mobs. You might be able to tack on an extra one or two with some lucky TC or Cleave hits, but in general it's better to just plan around that.
