Best of both worlds: Change it so if you double-click "User CP" it takes you straight to the control panel, and if you single-click it, it opens the popup. That way me and Zach can just double-click instead of single-clicking twice.
But that's the same number of clicks. And provided you can move your mouse accurately, you can do it with a double click as it is now. Try it.
My point exactly clicking twice in the same place is much easier and faster than clicking once, moving the mouse, and clicking again. Irregardless of your dexterity, the former is still easier & quicker than the later. In addition, we're already conditioned to do single and double clicks, so a single double-click is really no more effort than a single single-click.
And you can't do it as a double-click currently, the menu simply doesn't open fast enough. You try it

Bookmark the page if you need it that often that quickly.
An answer was already given to this suggestion...the benefits outweigh the single con (which is not really a con to begin with in my opinion). Users who just want to visit the User CP will have to take the few millaseconds required to click twice to acces it.
You could always open it in a new tab which would take you straight to the usercp page. (Ctrl+Click in FF or Middle mouse button/wheel click in FF/IE7)
