he's absolutely right, and it has bothered me before (but I don't use such 
large packages on a regular basis). If I recall correctly, I even timed this 
to be around 20% of the startup time of rkward (due to loading all the 
data.frames in the datasets package), so indeed, I'd like to find a solution. 
The question is: How to avoid this for lazy loaded (or rather promised) 
symbols, and only for those? I simply don't know a way to differentiate those 
from "regular" ones. Do you have an idea?

If you can give me a starting point?
