You can replace the pads (as stated elsewhere).  There are a lot of variations in pad material, and a faster-wearing pad is not necessarily a better braking pad.  Unfortunately, it's hard to find a good selection of pads, and even harder to get good info on which is suitable to which conditions.
You can use your rear brake more, especially for speed control, and save the front for more "serious" efforts.  When I'm on a downhill (rarely as steep/long as yours, though) I like to alternate between front and rear brakes for speed control, and I do it more in bursts rather than with steady pressure.  I'm not sure if this is "approved" technique, but it's what makes sense to me.
You can install a second set of calipers.  This is often done on tandems, and can be done simply on some bikes/with great difficulty on others.  (Of course, you'd need to figure out how to operate the extra set, without growing a third hand, and you do have to worry a little about the rim overheating.)
You can get disk brakes (though from the war stories I hear here it's not clear that they are really any better in such a situation).


Adjustment to road bike brakes for high grade downhill
I want to make a window that has an icon on the taskbar, but does not have the option to be closed from there.  I could simply intercept WM_CLOSE, but then a non-functional option still remains on the window's taskbar menu.  There are other questions on stackoverflow pertaining to that method, but none that describe how to hide the option itself.  How can I accomplish this?
