This glitch has been fixed with the November 30th update.

Maybe I have temporary reading-blindness, but I cannot find this in Notch's last
blog entry "Bug fixing made fun".
If you refer to "Swords and other weapons now deal damage properly", that means something different. Until now, according to Socrates, everything (incl. weapons) deals 1 point damage. I believe that this update will make a diamond sword hit like a diamond sword.
Anyway:
Once that bug is fixed (which it eventually will be), we should try to live with it for a while, and then we should decide if we want a mod for that: One that for example just quadruples the standard tool duration. Something like that. If one diamond pickax holds long enough to ensure that you find more than 3 more diamonds (on average), that would be cool.
I know, we could use stone pickaxes instead. I have played Single Player excessively like that. But I think Multiplayer is "faster", so to speak, and to creep along on stone pickax feet, that's not fitting imho. And anyway, I think that you even don't find enough diamonds in Single Player, if you think what you can do with them and that a diamond pickax is near useless (except for obsidian) since you can't use it more broadly because you have to save on diamonds. Additionally, I think it would be sad it you'd
have to power-mine instead of being more casual about it (without the parallel corridors etc). I always use the parallel method, but it makes that part of the game boring and tedious. Homework: Find diamonds. Meh. Also, the world is the size of EARTH (Surface.), somehow it doesn't feel right to squeeze one spot dry of every possible resource instead of being a bit more dancy about it.
In short: I think the duration you can use all tools should be quadrupled. Or the amount of diamonds in the world should be quadrupled. But the hoe dies too quickly, too, so I'd go with 4x tool duration. In single and multi player.
