I'm surprised noone's mentioned the upcoming Dungeon Delve book. And then there's the strategy of signing up for the RPGA and getting short adventures from there. (Edit: Kheti sa-Menik beat me to the latter.)
But no, Dungeon Magazine isn't optimal for one-shots.
To me it seems like this was a plant question to get people to start talking about the RPGA. EVERY RPGA adventure is designed to be a one shot (with some over arcing story that players can piece together if they play alot of them). Plus they are free, just sign up for the RPGA (free), take the DM test (open book and easy), and you can get them.
Plus there are the D&D game day adventures and the Free RPG day adventures as well. So for 4e that means, "Into the Shadowhaunt", "Against the White Dragon" (which is not really an adventure, more like an encounter), and "Treasure of Talon Pass". "Treasure of Talon Pass" is free on the WotC site.
As mentioned, the Dungeon Delve book is pretty much geared to be one shots. Also, in the Dragonomicon and in the upcoming Open Grave books they have a "Liars" section that you can easily run as quick "one shot"s.
